gollvm: fix some problems with GCC installation detection

Fix a couple of problems with the driver's GCC installation detector
that prevent it from working correctly for certain cross compilers. On
Debian, cross-compiler bits wind up in /usr/lib/gcc-cross, not
/usr/lib/gcc. There was also an off-by-one error in the code that
locates program paths for cross compilers.
