# The installation of the target runtime libraries defaults to DESTDIR, however
# host-clang resources directory needs a link so Clang can find the runtime
# libraries in the same location they would be if built as part of the Clang
# build. The "resources" directory is loosely documented and seems to be
# assumed, as compiler-rt is usually build at the same time as Clang and not
# standalone.
