 Personally, I would just avoid the "biarch"-ness (don't set
 CC and/or CFLAGS) and *some* of the automatic
 guessing of host/build/target and do this:

run config.guess
probably it will say sparc-sun-solaris2.9.

Then do this:

  mkdir /obj  
  cd /obj  
  /src/configure \
   -disable-nls \
   -build sparc-sun-solaris2.9 \  (ok, you can omit this line, -build is always correctly guessed in my brief experience) 
   -host sparc64-sun-solaris2.9 \
   -target sparc64-sun-solaris2.9 

 (Single dash options are clearly supported by configure.) 

Also, it is a bit of a time sink, but you can stick the gmp and mpfr source right into the gcc source tree and it'll build "all at once". (renaming mpfr-2.3.0 to mpfr, etc.) 
In fact, that might help you, since it'll net you sparc32 and sparc64 if needed.

This definitely won't be the quickest way.
Quicker would be to set CC/CFLAGS and use -disable-bootstrap.
