PATCH 1/1 Update qemu-binfmt-conf.sh

The patch updates the comments, makes modprobe conditional, adds a mount needed at least for Debian, and tries to add m68k.

I have no m68k executable available, perhaps somebody can check the header bytes and the cpu type for this platform?

Maybe the cpu list for mips must be completed, too.
