[cfe-dev] Clang support for Arch Linux

[Mulder, Jonathan]

Hi Chandler,

I had submitted a patch a while back for this that didn't get picked up, in
order to compile anything c++ related I also needed to include the attached
portion.

Note: I've only actually tried this on a 32-bit machine, but the 64bit path
was what I saw in the arch package when I checked online.

Also, I didn't need the Lib = "lib" chunk; although it doesn't seem to break
anything for me. Maybe that's needed for the 64bit?

Thanks,
Jon
