Subject[PATCH] binfmt_elf: Reorder objects in Makefile to favor platform default.
Reordered object list so compat_binfmt_elf.o comes first. This will make it
call register_binfmt() first, inserting it at the end of the list.

Now the kernel will try the compatibility formats as a backup if the actual
system format rejects the binary. As almost all binaries loaded won't be
compatibility formats, this saves a few cycles for each process.
