AC_PROG_CXX checks for several C++ compilers INCLUDING g++. When none
of them were found it sets the CXX variable to be g++. This doesn't
make any sense. Absense of g++ has already been made sure.
Because we don't want insanity (that's the whole reason we test the
environment using autoconf), we need to swipe such insane variable out.
