You should try first to make gcc as a  cross compiler to 
sparcv9-sun-solaris2.8: with a command string like this:

#./configure --host=sparc-sun-solaris2.8 --target=sparcv9-sun-solaris2.8
#make && make install

it should work fine and produce gcc that is itself a 32bit executable and 
produces 64bit executables and than and _only than_ you should make a fully 
64bit gcc. using previously built cross-compiler! 

#export CC="/usr/local/bin/sparcv9-sun-solaris2.8-gcc"
this will force CC to be crosscompiler to sparcv9-sun-solaris2.8 architecture
# ./configure --host=sparcv9-sun-solaris2.8 --target=sparcv9-sun-solaris2.8

and now:
# make bootstrap

everything should work just fine. you'll have to tweak some stuff abit but in 
general it should work.

good luck.
