At least for sh4, it would have a historical reason.  In the old
time, -m4-nofpu confused many users (including me).  From its name,
those users expected that it'll give the same ABI for integer only
programs with -m4 and fallen into the pit.  Then no one complained
when the default configuration was -m4 only for sh4-linux gcc and
the kernel folks satisfied with --with-multilib-list=m4,m4-nofpu.
