I've found that www/unit builds, primarily unit-perl* and unit-ruby

Here's the similar issue and bug report,
https://bugs.ruby-lang.org/issues/17865
From the other side, all 12 builds are successful with clang12.
Please note, that's not an issue with NGINX Unit itself, that's the
issues when clang13 builds unit-perl* and unit-ruby* modules, and
there's no issue with unit-python* modules.
So, the forehead solution is probably disable -Werror warning for
perl and ruby modules with a reinplace, but I see no reason to do
that for all 12 ports, that's why I'm looking for details how to
enable -Wno-compound-token-split-by-macro for a specific compiler
version.
Removing use of -Werror (for all ports) is the preferable solution here.
That's a good flag for the upstream developers to use so they have to
fix warnings, but all it does for our users is cause unnecessary build
failures.
