making C++ component on OSX

[verdiverdiverdi]

make will fail on OSX unless Makefile changed to

all:
clang++ -fPIC -Ofast -mavx2 -funroll-loops -std=c++11 -stdlib=libc++ -mmacosx-version-min=10.7 -c SubSieveLib.cpp -o SubSieveLib.o
clang++ -shared -Ofast -mavx2 -funroll-loops -std=c++11 -stdlib=libc++ -mmacosx-version-min=10.7 SubSieveLib.o -o SubSieveLib.so

because the depreciated libstdc++ will be used by default even with the most up to date XCode.

Thanks for the notice. I have a very specific makefile for my architecture indeed. I will add comments suggesting to adjust the makefile to user specific setups.
