Right.  Nowhere in the configure/build process do we try to propagate
configure flags down to the testsuite.  Consider if we did -- particularly
for things like "-O2" -- all the gcc tests suddenly test with -O2
which is definitely not what we want.

Lots of ways.  You can hack up unix.exp to pass additional arguments
or a local site.exp.  At least I think you can still hack the local
site.exp to arrange for args to be passed to the testsuite.
