But it can't link, necessarily.  We go through some perversions to make
sure that CXX is a C compiler; then testsuite/Makefile.am defines
CXXLINK with a cute little sed expression that might or might not find
you the right C++ compiler.  It does for native bootstraps, but I don't
know if it will for non-bootstraps; it definitely doesn't for
host-x-host builds where $CXX at this point is "mipsel-linux-gcc".
