Suppress AOUT library support in ELF binfmt if CONFIG_BINFMT_AOUT is not set.
The MN10300 architecture does not support the AOUT binfmt, so the ELF binfmt
should not be permitted to go looking for AOUT libraries to load.
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.
