[PATCH] disallow modular binfmt_elf32

Currently most architectures either always build binfmt_elf32 in the kernel
image or make it a boolean option.  Only sparc64 and s390 allow to build it
modularly.  This patch turns the option into a boolean aswell because elf
requires various symbols that shouldn't be available to modules.  The most
urgent one is tasklist_lock whos export this patch series kills, but there
are others like force_sgi aswell.

Note that sparc doesn't allow a modular 32bit a.out handler either, and
that would be the more useful case as only few people want 32bit sunos
compatibility and 99.9% of all sparc64 users need 32bit linux native elf
support.
