gtk4 @4.12.0: Should not need to blacklist clang < 1200

[ryandesign (Ryan Carsten Schmidt)]

gtk4 blacklists clang < 1200 because:

../gtk-4.12.0/gdk/x11/gdkglcontext-glx.c:666:56: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces]
                           (XSetWindowAttributes[1]) { 0, });
                                                       ^
                                                       {}
6 warnings and 1 error generated.

But the project is deliberately enabling warnings for this specific error (and others):

Compiler for C supports arguments -Werror=missing-braces: YES 

So the developers want to fix these problems, so it should be reported to them so it can be fixed and the blacklist can then be removed.

Alternately, if they will not fix the problem, we should remove -Werror for this warning, as we already do for another warning. (Why do we do that? Isn't that an upstream issue too?)

Yep, I agree, and will check with upstream. (This was simply a quick fix, to resolve the build issues for 10.14/10.15.)
