I suppose it did. It's not easy to cross-compile things (i.e. build
executables for platforms different from what you do the building), you
need to jump some hoops. And still, running such an executable is a
different story (e.g. you can cross-compile for Windows or an iPhone on
Linux - but running the resulting executables is a completely different
story).
