With an out-of-tree Clang, we can use the -resource-dir flag when linking to point it at the runtime libraries from the current SYSROOT. This moves the path to the clang-internal library directory to a separate .mk file that can be used by Makefiles that want to find the sanitizer libraries. I intend to re-use this .mk file for my upcoming changes that allow building the entire base system with ASAN/UBSAN/MSAN. Reviewed By: dim Differential Revision: https://reviews.freebsd.org/D28852
