RFC: PATCH: cxx_runtime option for macports.conf [was: Re: Host Versus MacPorts lib[std]c++]

[Jeremy Huddleston Sequoia]

I pushed this to trunk/base as r110369

I got pretty far last night without any major issues on my ML VM.  I just needed to autoreconf a few projects to update their bundled glibtool (older versions did not pass -stdlib=libc++ to the linker).

Unfortunately, issues with the VM unrelated to these changes have put a stall on my testing/fixing of ports in this category, but I'll get back to it eventually.

Since the barrier to entry is quite low (add "cxx_stdlib libc++" to macports.conf and rebuild), hopefully other interested developers can jump on board and fix ports that they use and/or maintain.

Thanks,
Jeremy
