Doesn't the clang driver already search for gcc libraries installed next to it? If you need it to be in a subfolder or something, I would prefer to add support for GCC_INSTALL_PREFIX being a relative path, so that you can build with something like

configure --with-gcc-toolchain=../relative/gcc/install/dir/

instead of doing prefix match at runtime.
