[PATCH] D37914: [OpenMP] Don't throw cudalib not found error if only front-end is required.

[Gheorghe-Teodor Bercea via Phabricator via cfe-commits]

gtbercea created this revision.

If we only use the compiler front-end, do not throw an error about the cuda device library not being found. This allows the front-end to be run on systems where no Cuda installation is found.
