ruby and python are, from Guix POV, not platform-independent code, as
they may have baked-in references to platform-specific binaries.
Their build systems don't support cross-compilation yet though ...

Always build-inputs -- some of the not-yet-cross-compiling build
systems do it different, but maybe they will gain cross-compilation
someday, and to do that, (standard-packages) needs to be in the right
place!  I've added some info to <https://issues.guix.gnu.org/54820>.
