There may be some confusion. The regular usage all works fine. - `clang++ foo.cpp` detects GCC installation. - `clang++ --gcc-toolchain=Inputs foo.cpp` detects GCC installation under Inputs. - `clang++ -BInputs foo.cpp` detects GCC installation under Inputs and `/`. With this patch `Inputs` is not used for detection. `Inputs` is still used for finding executables (ld, as) - `clang++ -BA --gcc-toolchain=B foo.cpp` detects GCC installation under A and B. With this patch, only B is used for detection.
