Is there anything that prevents NetBSD from jumping to GCC-10?

I think that sticking to old and unsupported GCC versions is rather
problematic as this way potential regressions in GCC will be found
very late.

In Debian, where I maintain the m68k port, we are currently using GCC-9
and switching to GCC-10 soonish.

I would prefer NetBSD switching to GCC-10 and it would be great if you
could upstream your GCC patches so that other downstream projects will
profit from these as well.
