GCC and LLVM collaboration

Do take a look at my LLVM Weekly newsletter http://llvmweekly.org/ (and/or follow @llvmweekly on Twitter) if you're interested in keeping up to date with LLVM developments.
If anybody wants to get stuck in to an interesting and meaningful open source project such as gcc/clang, things like the compiler driver (command line parsing+invoking the steps in the compilation process) are accessible to someone who can deal with gnarly code but perhaps isn't a compiler expert, and I think it's fair to see could benefit a lot from careful refactoring and better testing in both GCC and Clang.
There are some pretty cool things going on it seems, like the compile/inject stuff for GDB or libgccjit.
tl;dr: GCC and LLVM are collaborating to make some interfaces the same to make things easier for users.
Does anybody know of alternative proposals to the use of triples to describe compiler targets?
