Now that multiple prefixes are much cheaper to search for GCC
installations, support them when installed directly under the system
root ('/lib/gcc/...' essentially).
With this, Clang can correctly detect and use a cross-compiling GCC
installation within a system root and use it.
Again, test cases will be coming in later commits, as I'm going to write
a few test cases that exercise nearly all of this logic.
