Actually, I think I /want/ $CC to break in libstdc++-v3.  It'll be a
warning flag, since it shouldn't be used.

(Right now, we use it twice, but only the driver, not the actual compiler,
and I'll be changing it to use $CXX instead.)

Actually, we've got a couple of sparc tests going now, which are multilibbed
for real.

Absolutely.  I'm crazy, but I'm not insane.  :-)
