Feel free to add me as a reviewer.

I suspect the bug is that clang calls the target triple: 
"x86_64-unknown-linux-gnu" and gcc calls it: "x86_64-linux-gnu", and 
thus doesn't find the toolchain there.

Maybe for ".*-none-.*-.*" and ".*-unknown-.*-.*" triples we ought to 
search the corresponding ".*-.*-.*" directories?

The output from '-v' ought to tell you about which candidate gcc 
installations/multilibs it found, if everything is working correctly.


Cheers,
