The patches to configure --with-cpu-32= and --with-cpu-64= are availabe in GCC
6, so we should use them and ensure that the defaults for the sparc/64 and
sparc64, and sparc and sparc64/32 targets match. Just forcing ultrasparc for
all multilib variants seems to be questionable.
Btw, is there any business with the Debian sparc port, or is this just some
exercise?
