Since 846a29afb0 (config.mak.dev: workaround gcc 12 bug affecting
"pedantic" CI job, 2022-04-15), DEVELOPER mode has this workaround
for the version of gcc that was released with Fedora 36.
That version of Fedora is about to be EOL and latest versions of
the compiler don't have that bug anymore, so remove the workaround.
Tested not to trigger with latest gcc packages from the last 3
Fedora releases, including gcc 13 from Fedora 38.

The commit message doesn't explain the benefit of removing this
workaround. Is it because it's a maintenance burden? Or is it
preventing some future planned improvement in this area? What is the
justification for penalizing users who might be stuck on Fedora 36 for
some reason or another?
(I ask these questions as a person who regularly is stuck on old
platforms for which it is increasingly painful or impossible to build
or install modern software.)

The workaround was added for the benefit of the CI and to prevent
failures because the buggy warning will otherwise make it fail because
of -Werror when Fedora 36 was released and our CI started using it.
Our CI doesn't need it anymore to avoid that issue.

I certainly didn't intend on penalizing any users, but I frankly
suspect there aren't any, as the bug was fixed long ago, and it
wouldn't affect them unless no gcc updates were ever done on their
systems.

Our CI may not need it but what users of other distributions using gcc
12? The link[1] in the commit message for 846a29afb0 suggests that
debian was also affected at that time so the bug was not a fedora
specific. We could perhaps tighten the check if we know which specific
versions of gcc 12 are affected but it is not clear that removing it
entirely is a good idea.
