Well, it works for me:
/bin/bash ./libtool --tag=CC --tag=disable-static --mode=link cc -g -module -bindir /export/home/oracle/i/libexec/gcc/i386-pc-solaris2.10/4.6.1 -o liblto_plugin.la -rpath /export/home/oracle/i/libexec/gcc/i386-pc-solaris2.10/4.6.1 lto-plugin.lo -Wc,../libiberty/pic/libiberty.a
libtool: link: cc -G -h liblto_plugin.so.0 -o .libs/liblto_plugin.so.0.0.0  .libs/lto-plugin.o   -lc  ../libiberty/pic/libiberty.a

So it does know to use -G and -h instead of -shared and -soname. No idea 
why it's different for you.

Btw, I set CC=cc and used --with-gmp=... --with-gnu-as --with-as=/usr/sfw/bin/gas --without-gnu-ld --with-ld=/usr/ccs/bin/ld

Yes, that revision was only on trunk.

You would still need CFLAGS_FOR_TARGET I guess. Doesn't configuring with 
--with-arch=v8 or --with-arch-32=v8 work?
