How about breaking out the big system case construct from configure.in?

Also a big bonus for submitted patches, no massive line-number-change
diff to filter out.

Anyway, I did this for GDB several years ago, splitting out both a
configure.host and configure.tgt (since GDB has separate case
statements for host and target configure decisions), and it's been
very convenient.  I always wondered if GCC had some subtle reason
for not doing a similar split...
