Reverts r14831 - wasn't a valid fix.
Patches MiniUPnPc to explicitly export symbols for GCC/Clang, fixes build when -fvisibility=hidden is used, refs #2304.
Fixes incorrect use of CPPFLAGS in build-osx-libs.sh, it should be CXXFLAGS. CPPFLAGS get passed to the C/C++ preprocessor, CXXFLAGS get passed to the C++ compiler.
