I am supposed to build pkgs with Sun's compiler first and gcc only as a
last resort.  I know very little about gcc, so I can help on this.

Here is how I build the sparcv9 library.  Change references to /opt/csw
to whatever you need.
Source a file that contains the following.  Use the full path to Sun's
cc and CC if your path is wrong.  Also, do have /usr/ccs/bin in your
path for that version of make or use gmake.  I use make.  Do not have
/usr/ucb/bin in your path.

#!/usr/bin/sh
# 'compiler and linker flags'
CFLAGS='-fast -xtarget=ultra -xarch=v9'
export CFLAGS
CC=cc
CXX=CC
export CC CXX
ABI=64
export ABI

Then I run configure with the following statement:
./configure --prefix=/opt/csw --libdir=/opt/csw/lib/sparcv9
Then make and make install.

Building some of the various sparcv8 libraries is a bit trickier, but
you said you wanted sparcv9.
