bug#56738: Cannot find libgccjit.dylib on macOS

[Kevin Morio]

Dear Emacs maintainers,

Emacs 28.1.90 (282dde887db163b25b31fba3bf10a80f2b93203c) fails to build on
macOS 12.4 when configured with the following invocation:

./configure —with-native-compilation
...
usage: dirname string [...]
checking for gcc_jit_context_acquire in -lgccjit... no
configure: error: ELisp native compiler was requested, but libgccjit was not found.
Please try installing libgccjit or a similar package.
If you are sure you want Emacs be compiled without ELisp native compiler,
pass the --without-native-compilation option to configure.

This is the same bug as bug#55173 which has been reported for
  Emacs 29.0.50 (a41a181db5f3aca043ed42b228dc56a6403c21a5)
and fixed in commit
  faa29fa2c9e9d5a5d7544a1a39b2a89cf57a8439
with the following patch

diff --git a/configure.ac b/configure.ac

Thanks, I've now cherry-picked that change to the emacs-28 branch, and
it will be part of the upcoming Emacs 28.2.

No further comments within a week, so I'm closing this bug report.
