Subject: [PATCH 1/4] Include <asm/a.out.h> in fs/exec.c only for Alpha.

We only need it for the /sbin/loader hack for OSF/1 executables, and we
don't want to include it otherwise.

While we're at it, remove the redundant '&& CONFIG_ARCH_SUPPORTS_AOUT'
in the ifdef around that code. It's already dependent on __alpha__, and
CONFIG_ARCH_SUPPORTS_AOUT is hard-coded to 'y' there.
