I would love to do that for m68k as well. We could use this opportunity to
rebuild the m68k port with 32-bit alignment which would solve quite a number
of problems since many projects like LLVM and Qt assume a minimum alignment
of 32 bits while m68k still defaults to 16 bits.

Since the time64 rebootstrap would break the ABI anyway, we could use to fix
alignment issue on m68k once and for all :-).
