Clang attempts to guess file names based on the OS and distro (yes!),
but unfortunately, that doesn't work for us.
This patch makes it easy to insert libc's $libdir so that Clang passes the
correct absolute file name of crt1.o etc. to 'ld'. It also disables all
the distro-specific stuff and removes the hard-coded FHS directory names
to make sure Clang also works on non-GuixSD systems.
This patch makes slight adjustments over "clang-libc-search-path.patch" for
changes in clang 3.8.
