You can't have any logic based on the value of $CC (or $CXX), because `gcc`
might be a symlink to `clang` (as is the case by default on MacOS for instance,
but I've seen it on Linux as well), and users also use it to add compiler
flags.

As for the issue, do you guys see the same warning for any other -Wno-foo from
our list?
I'm 90% sure this is NOTOURBUG as we're already doing all the checks needed,
but I want to figure out if it's clang or autotools going bad.

Vinson, can you also try meson on your system? It would help narrow down the
issue.

(I've also checked that there's no typo in the configure.ac check, just in
case, and there isn't)
