Subject: [PATCH] [lld] Use installed llvm_gtest in standalone builds
Use the installed llvm_gtest library instead of rebuilding it locally
when standalone builds are used. This change is now required
as otherwise the build fails due to duplicate llvm_gtest target.
This is based on 82169103958583d3320b3a9a1e6542e8d32ef8da in clang.
