"x" is added for "${MAC_LIBS}" test, just in case.  Revised patch is
attached.  I also attach emacs-28 config.log's against both
homebrew libgccjit-12.1.0 and libgccjit-11.3.0.

Subject: [PATCH] Fix libgccjit library path lookup for Homebrew libgccjit
 12.1.0 and above

* configure.ac: Choose the first match from multiple libgccjit.dylib
paths in 'brew ls -v libgccjit' output.  Prefer 'current/libgccjit.dylib'
over '${ver}/libgccjit.dylib'  (Bug#57015)
