this behaviour is a result of the -fast argument to cc(1), which turns
on -xlibmopt.

one option might be to follow -fast with -xnolibmopt (which disables
the default -fast behaviour of using the optimized math library) or
add "-B static -lsunmath -B dynamic" whenever -fast and -lm are
passed.

of course, another bigger issue with the use of -fast -fast (and other
compiler flags) is that binaries will not run on earlier processor
family systems than they were built on.
