New Revision: 291991

URL: http://llvm.org/viewvc/llvm-project?rev=291991&view=rev
Log:
Don't dump llvm-config --cmakedir output if command fails.

This patch adjusts the out-of-tree CMake configuration so that
the stderr output is ignored when an old llvm-config is found
that doesn't support --cmakedir.
