IIRC, Gentoo Linux provides a cc wrapper that is able to call any compiler,
based on how you configure it.  There is a "cc-config" (or something similar)
program that can be used after installing multiple compilers to select the
default one.  Such an approach might be better, IMO, as you don't have to
handle "shared" files across multiple packages.
