./tools/build/cross-build-macos.sh is a wrapper for ./tools/build/make.py on macOS - to make it easy to compile FreeBSD on macOS.

• support multiple LLVM versions (clang19 and clang20)
• supports Apple M1 arm64 and Apple/Intel
• supports concurrent cross building (e.g. current and stable at the same time with same MAKEOBJDIRPREFIX)
• supported make targets: buildworld; buildkernel; packages; -C./release ftp
• by default it runs fast (no toolchain etc.) for buildworld + buildkernel
• add a help message: ./cross-build-macos.sh help
• keep up to 32 logfiles
• add a debug mode (debug=1)
• keep track of good/bad git commits in .cross-build-macos-git-*
• supported branches: main, stable/15 (buildworld + buildkernel)
• tested on macOS 14.x, 15.x, 26.x
