Clang allows a full path to be passed to -fuse-ld=. However, GCC (and others?) don't allow this. If gold or lld is selected, the linker is not on a standard path (e.g. Gentoo, which allows multiple versions of LLVM to be installed in /usr/lib/llvm/<major>/) and --incompatible_strict_action_env is enabled, GCC won't know where the linker is located and fail to find the linker. Now we always return the full linker path, and pass -fuse-ld= based on the compiler identity. Fixes bazelbuild/bazel#26527.
