Thanks for the explanation. I got it to build by specifying exactly that,
-mcpu=v9 -m32, which resulted in v8+ binaries.

For those interested, here's my set of Boost packages compiled on Solaris
10, for sparc and intel architectures:

http://buildfarm.opencsw.org/experimental.html#boost

Here's the build recipe:
https://gar.svn.sourceforge.net/svnroot/gar/csw/mgar/pkg/boost/branches/boost-gcc/Makefile

Each shared library is in a separate package, so if you build something
depending on Boost, you only need to depend on a small package instead of a
big bundle. There are 32-bit and 64-bit libraries, under /opt/csw/gxx/lib
and /opt/csw/gxx/lib/{sparcv9,amd64}.

If anyone's interested in trying them, I'll be happy to get feedback.
