It's taken quite a long time to sort out the bugs in gcc-5 with regard to
lesser-used arches, so I've only just managed to get cross-gcc in rawhide
upgraded to gcc-5, despite the main gcc package having got there a while ago.
Is it too late in the F22 cycle now to upgrade cross-gcc there to gcc-5? I'm
not entirely sure what depends on it or how to find out?
