[libcxx] r323453 - [cmake] [libcxx] Call llvm_setup_rpath() when adding shared libraries.

[Duncan P. N. Exon Smith via cfe-commits]

I don't really understand why, but our bots seemed to survive this:
http://lab.llvm.org:8080/green/view/Libcxx/job/libcxx_master_cmake/2137/ <http://lab.llvm.org:8080/green/view/Libcxx/job/libcxx_master_cmake/2137/>

Console output is here:
http://lab.llvm.org:8080/green/view/Libcxx/job/libcxx_master_cmake/2137/consoleFull <http://lab.llvm.org:8080/green/view/Libcxx/job/libcxx_master_cmake/2137/consoleFull>

That doesn't necessarily mean it's safe.  Does anyone know why this might have "worked"?
