The problem is that gcc in stage 2 is linked by GNU, and by defualt,
gcc believes that you have a floating point unit.  If you change the
macro TARGET_DEFAULT in tm-sun3.h, you should be able to build.

Revisions previous to 1.31, you had to also modify the spec files
which specify which /lib/?crt[10].o gets linked in as well, but that
was fixed in 1.31.
