We really need COMPAT_AOUT_M68K option to adjust
alignment incompatibility between a.out and ELF,
but -current COMPAT_AOUT_M68K handles both real
a.out incompatibility and /emul/aout path search.

New COMPAT_AOUT_ALTPATH option allows disabling (or enabling)
/emul/aout alternate path search of COMPAT_AOUT_M68K,
and it should be disabled by default as you said.

IMHO, old COMPAT_AOUT option should also be renamed to
COMPAT_AOUT_ALTPATH (or something), but I don't think
we can share syscalls.master files among the archs
for this option.
