I was surprised to learn that a compiler from the host machine was
potentially being used as part of a build, not which one is found and
being used. When I discovered this I was quite sure I had configured
something incorrectly. This is more of an academic exercise, I didn't
run into any problems.

I guess we're covered in the sense that each release specifies which
distros are supported. So as long as any native tools that are used in
each of the support distros are able to produce a successful build
everything should be fine. BUILD_CC is almost like an implicit
ASSUME_PROVIDED.
