Deprecate a.out ELF interpreters
The Linux ELF loader is quite complicated and messy code (that could
probably need a rewrite, but that's a different chapter). One particular
messy part in it is the support for non ELF a.out ld.sos. This was
originally added to make transition from a.out to ELF easier because an
a.out ELF ld.so could be still build using an older a.out toolkit. But by
now that should be fully obsolete and removing it would clean up
binfmt_elf.c up a bit.
I propose to deprecate this support and remove for 2.6.25.
Drawback is that someone still runs their system with a.out ld.so
they would need to update the ld.so when updating to a new kernel.
This patch just adds an entry to the deprecation file and a printk
warning users.
