target/Config.in.arch had become too long, and we want to remove the
target/ directory. So let's move it to arch/ and split it this way:
* An initial Config.in that lists the top-level architecture, and
sources the arch-specific Config.in.<arch> files, as well as
Config.in.common (see below)
* One Config.in.<arch> per architecture, listing the CPU families,
ABI choices, etc.
* One Config.in.common that defines the gcc mtune, march, mcpu values
and other hidden options.

This directory groups the following elements:
* the default root filesystem skeleton
* the default device tables
* the Config.in options for system configuration (UART port for
getty, system hostname, etc.)
* the make rules to apply the system configuration options
Even though the skeleton and device tables could have lived in fs/, it
would have been strange to have the UART, system hostname and other
related options into fs/. A new system/ directory makes more sense.
As a consequence, this patch also removes target/Makefile.in, which
has become useless in the process.

As stated in commit 555c2585bf28c3ef71f6d2dcdd983d17a19892af, the
Xtensa architecture has been introduced in 2009 and never changed
since its initial introduction. It requires some special handling that
is a bit annoying, and despite our call to the initial developers, and
the announcement of the deprecation of the architecture during the
2012.05, nothing has happened. Therefore, drop support for this
architecture.

BR2_ARM_TYPE is a hidden configuration option that is only used for
the configuration of uClibc, therefore, we move it from
target/Config.arch.in to toolchain/uClibc/Config.in.
We also add a comment that explains that this stuff is only useful for
uClibc <= 0.9.32. Starting from 0.9.33, uClibc build process simply
uses the compiler flags to find the ARM processor that should be
used. So, someday, we'll be able to remove this.

Practically speaking, MIPS has three useful ABIs:
* o32 is for 32-bits CPUs, or 64-bit CPUs running only a 32-bit subset
of the instruction set.
* n32 is for 64-bits CPUs only. It has 32-bits pointers and long
integers.
* n64 is for 64-bits CPUs only. It has 64-bits pointers and long
integers.
See http://www.linux-mips.org/wiki/MIPS_ABI_History and
http://www.linux-mips.org/wiki/WhatsWrongWithO32N32N64 for more
details.
So, this commit reworks the Buildroot MIPS support by:
* Add separate mips64/mips64el top-level architectures.
* Renaming the n32 ABI option to BR2_MIPS_NABI32, for consistency
with BR2_MIPS_OABI32.
* Renaming the n64 ABI option to BR2_MIPS_NABI64, for consistency
with BR2_MIPS_OABI32.
* Make the n32 and n64 ABI selections select the BR2_ARCH_IS_64,
since those ABIs are valid on 64-bits CPUs only.
* Removing the o64 ABI, which is practicaly never used.
* Removing the "none" ABI, which really doesn't make sense.
* Introduce the mips64 and mips64el architecture names when a 64-bits
MIPS ABI is choosen. This will fix build issue like
http://autobuild.buildroot.org/results/9b8c5ea86c953a89e85e7b67e9221de41773f652/build-end.log
where gmp was confused by the fact of having a 32 bits architecture
(detected by the mips- architecture part of the tuple) but 64 bits
integer size when compiling.
* Adjust the uclibc.mk logic to support the new mips64/mips64el
architecture names, and take into account the renaming of the ABI
options.
This has been build tested by generating Buildroot toolchains and
compiling a few packages for MIPS o32, MIPS n32 and MIPS n64.
This work is originally based on prior work done by Gustavo Zacarias.

Instead of having two separate list of choices for select the target
architecture variant for i386 and x86_64, with many CPU choices
duplicated (because all modern x86 CPUs can be both used as i386 or
x86_64), merge them into a single list. In the x86_64 case, all the
x86 CPUs that do not support the 64 bits instruction set are hidden.

Since we have now two uncompatible init systems, and we want only one of
them at the same time in use in the rootfs, we need to select a
particular init system. This patch also adds $(PKG)_INSTALL_INIT_SYSTEMD
and $(PKG)_INSTALL_INIT_SYSV hooks that are called when the matching
init systems are selected to install properly the init scripts of the
package.

The FLAT (Separate Data) and FLAT Shared ABIs are rarely used, and the
FLAT Shared ABI requires the user to manually assign an unique ID to
each shared library, which we will never support in
Buildroot. Therefore, restrict ourselves to FLAT and FDPIC.
In addition to this, ensure that when FLAT is selected, only static
libraries are produced, because this is what FLAT supports. It will
fix problems such as
http://autobuild.buildroot.org/results/2d756d75162e8737e99df8189bde93ed1a09feef/build-end.log.
Moreover, we make FDPIC the default ABI, since if someone is using
Buildroot, it's most likely to generate a fairly elaborate embedded
Linux system, on which shared libraries are probably useful.

Changes:
- Linux kernel requirement: 2.6.34 and above (devtmpfs is mandatory)
(this also applies to the chosen toolchain, because of Kernel headers)
- optional dependency on libusb and usbutils removed
- added dependency on kmod
- added dependency on util-linux for libblkid
- install in /lib/udev instead of /usr/libexec/udev
- udevd moved to /lib/udev
- fixed path to pci.ids and usb.ids
- persistent rules generator is disabled by default, so option
is introduced to enable this option if desired

Add the ability for buildroot to build an SPE ABI enabled toolchain.
This is mandatory for e500v1/v2 cores since they don't support classic
FPU mode as the e500mc does.
Useful for Freescale's PowerQUICC III and single/dual-core QorIQ
line of processors.
The new TARGET_ABI variable is used rather than TARGET_CFLAGS for
uclibc's UCLIBC_EXTRA_CFLAGS to avoid breakish CFLAGS leaking in, a
good example being -mthumb for ARM.

[Fixes by Thomas, including comments from Arnout:
* Use AUTOTARGETS instead of GENTARGETS
* Use $(KERNEL_ARCH) instead of $(BR2_ARCH) as argument to the
prepare-kernel.sh script. This allows the arch name to be fixed
with the usual sed expressions and the quotes to be stripped.
* Add the --verbose option to prepare-kernel.sh. This allows to get
some clear error message when no Xenomai patch has been found for
the current kernel version.
* Improve the help texts as suggested by Arnout, and remove the
now useless README file.
* Add a BR2_PACKAGE_XENOMAI_SMP option, instead of poking inside the
kernel configuration to find out whether SMP is enabled or
not. This cannot work because: 1) the kernel might be built
outside of Buildroot and 2) if the kernel is built inside
Buildroot, it is built *after* Xenomai, so the kernel
configuration file is typically not yet present.
* Simplify the ARM subarchitecture selection as suggested by Arnout.
* Remove the documentation and development files according to
Buildroot standards (using BR2_HAVE_DOCUMENTATION and
BR2_HAVE_DEVFILES).
* Simplify the /etc/ld.so.conf modification logic.
