There's another set of architectures which have <asm/a.out.h> but don't
define ARCH_SUPPORTS_AOUT. Including PowerPC.

I think we can probably get away with removing <asm/a.out.h> from every
architecture other than Alpha, ARM, m68k and x86, and killing
ARCH_SUPPORTS_AOUT completely.

Or maybe, as dhowells suggests, re-defining ARCH_SUPPORTS_AOUT to be set
only on Alpha, ARM, m68k and x86 (so BINFMT_AOUT can depend on it).
