Suppress A.OUT library support 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 one of:
CONFIG_BINFMT_AOUT=[ym]
CONFIG_IA32_AOUT=[ym]
CONFIG_BINFMT_AOUT32=[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) Moves aout_dump_thread() into asm/a.out-core.h and makes it inline. This
is then included only where needed. This means that this bit of arch
code will be stored in the appropriate A.OUT binfmt module rather than
the core kernel.
(5) Removes a lot of now obsolete {linux,asm}/a.out.h inclusions.
(6) Drops A.OUT support for Blackfin (according to Mike Frysinger it's not
needed).
