cxx11 1.1 port group / -stdlib=macports-libstc++ may not be setting up paths correctly for i386 builds

Ken Cunningham
Yeah, well this one may well be NTBF, but I thought I would mention it.

During a recent buildbot build of Pingus using the cxx11 1.1 PortGroup on i386, the build fails with an error suggesting that when building with clang-4.0 against libstdc++ from libgcc6, in i386 mode, the proper flavour headers aren't found.

I would suspect if we dug into the path settings in Marcus' macports-libstdc++ modifications, we might find that this situation isn't covered. (I had to do some finagling with the paths to make this issue work out on clang-3.8 PPC as well.) I'm not sure how much interest there might be in covering off this corner case. -- Ken
