Sounds like you want a policy that:

    "-pthread" should not be supported when targeting FreeBSD 5.{2-9}
    using FSF GCC 3.3.2 (and 3.3.1 in /usr/src).

You would also like to not support "-pthread" when targeting FreeBSD 4.x.
I'm not convinced that we really can remove it there.  Also that will
make FSF GCC 3.3.2 not accept the same options that the system FreeBSD
4.x compiler does.  Can we live with tolerating "-pthread" when targeting
FreeBSD 4.x by any version of FSF GCC?

If so, an acceptable diff would be to only change the FBSD_LIB_SPEC w/in
the "#if __FreeBSD_version >= 500016" block.  Turning "-pthread" into a
NOP + warning would be nice, but the error output code you replaced the
entire FBSD_LIB_SPEC with would be OK too I guess.  The comment
addressing "At __FreeBSD_version 500016 and later,..." should be updated.
Can you commit such a change?  I'll get it into the right FSF GCC
person's hands for GCC 3.3.2.
