The GNU binutils ld linker needed a patch after the tagging of 2.38 to make the new feature work. Before this patch, the linker will fail to link when protected visibility symbols are used in the library, so don't enable the feature unless the linker is recent enough. GNU binutils gold from that version passes this test. LLVM lld is unknown (I didn't test), but LLVM was consulted in developing the feature.
