sanitize ifdefs in binfmt_aout
They are actually alpha vs. i386/arm/m68k i.e. ecoff vs. aout.
In the only place where we actually tried to handle arm and i386/m68k in
different ways (START_DATA() in coredump handling), the arm variant
works for all of them (i386 and m68k have u.start_code set to 0).
