Add linux/elfcore-compat.h
This adds the linux/elfcore-compat.h header file, which is the CONFIG_COMPAT
analog of the linux/elfcore.h header. Each arch that needs to fake out
fs/binfmt_elf.c for its compat code can use this header to replace the
hand-copied definitions of the compat variants of struct elf_prstatus et al.
Only the pr_reg field varies by arch, so asm/{compat,elf}.h must define
compat_elf_gregset_t before linux/elfcore-compat.h can be used.
It's a clean-up that every arch with compat core dumping code can benefit
from. I only touched the ones I have handy to test at home. Doing the same
for each other arch should be straightforward, and I'm happy to offer tips.
