Subject: [PATCH] Makefile: Don't try to add '-fcatch-undefined-behavior' flag
Date: Thu, 9 May 2019 04:48:25 -0700 [thread overview]

This is no longer a valid option in clang, it was removed in 3.5, which
we don't support.

Let me know if you want this incremental to your patch. I figured it
made more sense to remove this then do the cc-option/cc-disable-warning
removal because it will simplify the commit message.
