kbuild: refactor final link of sparc32
sparc32 uses an additional final link to support btfix. Introduce a new set of exported variables in the top-level Makefile to make the extra linking step simpler. sparc32 has hardcoded knowledge of kallsyms support. This fix include support for EXTRA_KALLSYM_PASS=1. The ugly part is that it is hardcoded in the arch/sparc/boot Makefile. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: "David S. Miller" <davem@davemloft.net> Signed-off-by: Michal Marek <mmarek@suse.cz>
