This is the companion patch to D133406 <https://reviews.llvm.org/D133406>, intended to get the ideas of `clang` of `compiler-rt` where runtime libs are located with `-DLLVM_ENABLE_RUNTIMES` in sync.  Both patches were necessary to run the release builds/tests for Solaris/amd64 and Linux/sparc64.

Tested on `amd64-pc-solaris2.11` and `sparc64-unknown-linux-gnu`.

This patch is **not** ready for prime time: right now it causes two regressions:

  Clang :: Driver/baremetal.cpp
  Clang :: Driver/print-libgcc-file-name-clangrt.c

where the patched driver uses `-triple thumbv7m-vendor-none-eabi` instead of the expected `armv7m-vendor-none-eabi`.  I have not yet tried to investigate this in detail, just wanted to get the patch out for reference.
