No, that was written under the assumption that passing in CC and CXX via
env variables wouldn't work. Things work now, so that assumption is
obviously wrong.

I still don't like environment variables. They tend to remain in effect
long after I forgot that I set them, creating all sorts of hassle. In
fact I suspect I already fell prey to this, getting llvm to compile and
check one day and nearly despairing when trying to reproduce that
success on the next day.
But, well, you use what you need to use to get the job done, so
there :-)
