Suppress A.OUT library support in ELF binfmt if CONFIG_BINFMT_AOUT is not set.
Not all architectures support the A.OUT binfmt, so the ELF binfmt should not
be permitted to go looking for A.OUT libraries to load in such a case. Not
only that, but under such conditions A.OUT core dumps are not produced either.
To make this work, this patch also does the following:
(1) Makes the existence of the contents of linux/a.out.h more or less
contingent on CONFIG_BINFMT_AOUT=[ym] or CONFIG_IA32_AOUT=[ym].
(2) Moves STACK_TOP[_MAX] out of asm/a.out.h and into asm/processor.h as
they're required whether or not A.OUT format is available.
(3) Renames dump_thread() to aout_dump_thread() as it's only called by A.OUT
core dumping code.
(4) Makes aout_dump_thread()'s existence contingent on
CONFIG_BINFMT_AOUT=[ym].
I suspect certain other arches that have an aout_dump_thread() function can
dispense entirely with it as they don't and won't support A.OUT.
