You can edit the *cpp and *lib specs.  In GCC 3.0, on Solaris/x86,
they will contain:

  %{pthreads:-D_REENTRANT -D_PTHREADS} \
  %{!pthreads:%{threads:-D_REENTRANT -D_SOLARIS_THREADS}} \


   %{!shared:\
     %{!symbolic:\
       %{pthreads:-lpthread} \
       %{!pthreads:%{threads:-lthread}} \
       -lc}}


I had failed to note you were using Solaris/x86.  -pthreads already
works in GCC 2.95.2 on Solaris/sparc, but these options weren't
introduced on Solaris/x86 too, probably because of an oversight, to be
corrected in 3.0.
