kconfig: Add error handling to KCONFIG_ALLCONFIG
- Only try to read the file specified if KCONFIG_ALL_CONFIG is set to
something other than the empty string or "1".
- Don't use stat to check the name passed to conf_read_simple so that
zconf_fopen can find the file in the current directory or in SRCTREE
removing a extremely source of confusing failure, where KCONFIG_ALL_CONFIG
was not interpreted with respect to the directory make was called in.
- If conf_read_simple fails complain clearly and stop processing.
Allowing the simple debugging of typos.
- Clearly document the behavior so it is clear to users which
values are treated as flags and which values are treated as
filenames.
