IMHO the most correct way to fix this problem is in CMake itself. If
it's cross-compiling and there's a $TARGET_PREFIX-pkg-config in path,
then it ought to use it automatically.

I'm not volunteering to champion that solution though. :-)

So of course the next best thing is to make Guix's build system do that
for us.
