I don't have 2.9 to play with but the following works for me on 2.8:

    CC="gcc -m64" ~/cvs/gcc31/configure --enable-threads=posix \
        --disable-checking --disable-nls --with-cpu=ultrasparc \
        sparcv9-sun-solaris2.8 \
        && gmake -j4 bootstrap CC="gcc -m64"

using Sun's as and ld and CVS GCC3.1.1 sources from the middle of last
week (release 3.1 ought to work too). gmake is GNU make - haven't tried
Sun's make. This build didn't include Ada; I've got Sun ld vs Ada symbol
problems and GNU ld 64-bit vs patched libdl.so problems but I haven't
yet found time to work out what bugs I need to report to whom.

For day to day use, though, I'd stick to the default 32-bit version and
-m64.
