Return a new CCompiler instance.
CCompiler used to be constructible via `distutils.ccompiler.new_compiler`,
but this API was removed as part of the distutils deprecation. Instead,
we trick setuptools into instantiating it by creating a dummy Distribution
with a list of extension modules that claims to be truthy, but is actually
empty, and then running the Distribution's build_ext command. (If using
a plain empty ext_modules, build_ext would early-return without doing
anything.)
