[cfe-dev] Supporting multiple targets from a single 'clang' installation

[C Bergström via cfe-dev]

For our out-of-tree madness (which I'll push a bunch of patches public
very soon) we do the following
----------
TLD/{VERSION}/lib|include/{PLATFORM}/{TARGET}/{BITS}/

So it looks something like this
clang/4.0.0/lib/solaris/x86_64/64/libc++.so


This allows cross platform, multiple versions, 32/64 bit as well as
multiple targets to all play nice inside the same prefix.


Keep in mind that you'll also need libc/m, linker and a few other
things for this to actually work.
