[cfe-dev] Small patches to allow fully independent clang/llvm/compiler-rt/libc++

[James Y Knight via cfe-dev]

I'd missed that thread, sorry! It's great that there's some agreement, at
least! :)

I think the key to getting something accomplished here is to keep it
simple: clang has command-line options already. If the configuration file
can be purely a way to get extra args included by default for certain
targets, it can be a *really* straight-forward change to make.

It seems to me mainly a question of defining exactly what conditions can be
predicated on when choosing whether to add some args.
