Fred Sundvik 7c9fff59d0 Fix slight inconsistency
When running make from either a keyboard folder or a subproject
it runs all keymaps for all subprojects and the selected subproject
respectively. Without this fix, the same doesn't happen if your
run make clean for example. As it would just provide you with an
error message. Now this will work as expected.
