The solution to get libgccjit properly working, and embedded in Emacs.app included: - The contents of GCC's lib folder (`/usr/local/opt/gcc/lib`) is copied into the `Contents/MacOS/lib-<arch>-<os_version>` folder. - Setting `LIBRARY_PATH` environment variable to correct GCC lib folders within Emacs.app. This is done through a bash launcher script which replaces the regular `Contents/MacOS/Emacs` executable. The main Emacs executable itself is named `Emacs-bin` now instead, so anything that depends on the exact process name will need updating. - The launcher script also adds `Content/MacOS/bin` and `Content/MacOS/libexec` folders to the PATH environment variable, to so ensure binary tools packaged into Emacs itself are available. This is done even when not doing a native-comp build. The launcher script skips setting LIBRARY_PATH if it's not a native-comp build. This should hopefully resolve both #5 and #7.
