Created attachment 225037 [details]
Apply upstream fix for building against libc++ 12

During an exp-run for llvm 12 (see bug 255570), it turned out that mail/thunderbird does not build with clang 12.0.0 [1]:

             ^
1 error generated.

This is caused by thunderbird doing a lot of complex and fragile juggling with system headers, and was reported upstream as <https://bugzilla.mozilla.org/show_bug.cgi?id=1694575>, then fixed via <https://hg.mozilla.org/mozilla-central/rev/f875a4ffd653>.

The fix is the same as bug 255953 for www/firefox-esr.
