PSARC 2014/183 Python 2.7.6 18251953 update Python 2.7 line to version 2.7.6

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.
