That's not the question (but one reason why Solaris 8 support will be
removed after GCC 4.7).  As Jonathan documented, you can't run S8 on a
bare 80386, so there's no reason the default code generation to that CPU.

Quite the contrary: leave out any configure option unless you absolutely
need it because the defaults don't work, document why you need them, and
re-check that info for every release.  If you think configure should
detect the condition on its own, file a bug report for that.

These `I've used them for ever' options tend to do more harm than good,
and confuse other users that check how your copy of gcc was built.  This
is especially bad for distributors like yourself, since the number of
confused people is far larger than for some company-internal build ;-)
