Unfortunately I have no idea. It might possibly help to use --disable-bootstrap
or --disable-multilib when configuring (just guessing here).

In general, if you have trouble building GCC, you might get help from
gcc-help@gcc.gnu.org (or, for Fortran-related things: fortran@gcc.gnu.org).

Note that some people offer nightly builds of the GCC trunk, see
