Do any platform-specific customization of a compiler instance.

Parameters
----------
dist : object
This parameter is not used for anything.
need_cxx : bool, optional
Whether or not C++ has to be compiled. If so (True), the
``"-Wstrict-prototypes"`` option is removed to prevent spurious
warnings. Default is False.
