changed: add option for using clang with libstdc++

Browse Source 
when using clang, whether or not we should link to stdc++fs
cannot easily be detected. it depends on the c++ lib used
(libstdc++ vs libc++), as well as the versions of these.

to avoid messing up in general, this adds an option for forcing
linking to stdc++fs, even when using clang. it defaults to false
to not break existing build setups where it works. is required
for building on jenkins
