No patch needed for 4.7.4 or 4.5.4? You may want to disable these versions for
m68k if you don't feel like testing it.

This should definitely be split into a couple of patches:

1. Unbreak m68k (changes to arch, gcc, uclibc)
2. Add binfmt-elf support
3. Add glibc support
4. Add aranym board

It would also be nice to add a qemu build, since qemu is more common.
