Use LLD w/ Clang for Universal builds
I recently reset my Windows machine toolchain and the Clang built universal binaries started crashing. The fix is to have the Makefile add ```-fuse-ld=lld``` to the final link for Windows Clang universal builds. This uses LLVM’s linker instead of GNU’s linker, which produced a crashing executable from the same object files. I don't know why it didn't show up for me before but most likely my old Clang installation used LLD by default so the Makefile didn't need to specify it.
