This changes Python's standard profile-guided build target to work with

Studio instead of gcc. The unfortunate repetition of options seen below

is a workaround for build peculiarities and to meet Studio's requirement

that the profiling options be used at all steps of the build -- not just

compilation. As it is Solaris-specific, it is not suitable for upstream.
