[libcxx] r220463 - Add -ldl to libc++ tests when sanitizers are used.

New Revision: 220463

URL: http://llvm.org/viewvc/llvm-project?rev=220463&view=rev
Log:
Add -ldl to libc++ tests when sanitizers are used.

Clang 3.6 no longer links the sanitizer runtime library dependancies when
-nodefaultlibs is used. This patch manually links in a missing dependancy.
