Eeeuuuuccch.  I'm not at all keen on dumping x86-specific stuff into
the generic header.  It's used on platforms other than just i386.  If we
make "generic" magically aware of i486s, we're doing an end-run around
the confirguration machinery.  Might as well put /all/ of the supported
platforms in this one file and use #if to distinguish them.
