Respect flag '-mmacosx-version-min=*' from lib makefile

Browse source 
Makefile.pdlibbuilder sets a default minimum OSX version for optimal
support of older OSX versions. With this commit, '-mmacosx-version-min=*'
in variable 'cflags' from the lib makefile is respected, not overridden.

A lib makefile can now determine the minimum OSX version (for example to
support C++11, which was the direct motivation for this change).

This is a response to pull request #22 'Making minimum Mac OS X version
configurable', but note that it is implemented in a different way.
