MaskRay added a comment.

Probably no from my view, as I got another internal feedback that "this seems rather crufty".
It seems that it is the build system maintainer's responsibility. If you add `-Wno-unknown-warning-option` temporarily, after a new clang is rolled, you may remove `-Wno-unknown-warning-option`.
