bpo-40637: Do not emit warnings for disabled builtin hashes (GH-20937)

stratakis · web-flow · commit 236a0f5cf022 · 2020-06-17T10:26:08.000-07:00
test_hashlib emits some warnings when it cannot find some hashes as it assumes they failed to compile. Since we can disable hashes through configure, we emit the warnings only in the case that we did not intentionaly disable them. Automerge-Triggered-By: @tiran
