I'm trying to build freehdl on build8s, but when it's linking the final
binary I'm getting an error about a missing symbol "__sync_fetch_and_add_4"
This seems to be a function that use atomic instructions that's not on i386
and sparc 8 so i686 has to be used. I assume the problem is similar on
sparc, but I have no idea which flags to use. Does anyone know?

I just saw the same problem:
...
Undefined first referenced
symbol in file
__sync_fetch_and_add_4
/home/maciej/src/opencsw/pkg/googletest/trunk/work/build-isa-sparcv8/gtest-1.4.0/lib/.libs/libgtest.so
I've stumbled upon the same problem, but also found the way to solve it.
Instead of having -mcpu=v8 as a compiler option, replacing it with -m32
will solve it.
