As per Jeff's suggestion, I removed the --with-cpu option and the build
completed successfully without any further issues; of this, I am grateful.

However, on a whim, I installed the new binaries, then tried to rebuild
gcc with the following configure:

CC="gcc -m64" ../configure --with-cpu=ultrasparc --prefix=/usr/local/gcc64 sparcv9-sun-solaris2.8

Things went well during the first stage, and into the second, until this
point:

stage1/xgcc -Bstage1/ -B/usr/local/gcc64/sparcv9-sun-solaris2.8/bin/ -c -DIN_GCC    -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long  -DHAVE_CONFIG_H    -I. -I. -I../../gcc -I../../gcc/. -I../../gcc/config -I../../gcc/../include ../../gcc/expr.c -o expr.o
xgcc: Internal error: Segmentation Fault (program cc1)
Please submit a full bug report.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
gmake[2]: *** [expr.o] Error 1

It took quite a while (nearly 10 minutes) before it errored out, so it
looks like gcc may not be sufficient to build itself in full 64-bit.  If
additional information is desired regarding this, I can produce it.

Once again, thanks for the help; it looks like there's a light at the end
of the tunnel for 64-bit support on Sparc with gcc.
