-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.
