They would need to add something like "%/CRC32C.o: COMMON_FLAGS +=
-msse4" to prefix.darwin too (clang should have compatible switches)

For Windows It is complicated as it depends if the particular VS
version supports the instructions or not, but you need to add some
compile switch too...

That's only for compiler - in addition you also need run-time
detection, but I see this is already covered by SSE4_2Supported()
method.
