[PATCH] D38665: [CMake] Fix linker detection in AddLLVM.cmake

[Rui Ueyama via Phabricator via llvm-commits]

ruiu added a comment.

I mean -DLLVM_USE_LINKER=lld is a valid option, so when it failed due to the lack compiler support of -fuse-ld=lld, it should be reported as a meaningful error, instead of a cryptic "CMake failed to compile this program blah blah." message. I think that is also true to the case when you pass -DLLVM_USE_LINKER=gold but gold was not installed to your system.
