[PATCH] fix create_elf_tables on PPC

create_elf_tables in fs/binfmt_elf.c now sets up the list of aux table
entries in a buffer on the kernel stack before copying it to the user
stack.

Unfortunately, while the buffer is big enough for most architectures, it
isn't big enough on PPC, which uses 5 extra aux table entries (put on
with ARCH_DLINFO).  The following patch increases the buffer to be big
enough for PPC.  (Note that each aux table entry uses two elements of
the elf_info array.)
