Important changes:
- Switch mergerfs and vendored libfuse Makefiles to -std=c++20.
- Select the latest available GCC/G++ or toolset in container builds.
- Verify compiler C++20 support during package installation.
- Fix dynamic SysLog formatting for fmt C++20 checks.
- Fix typo in static.installer: /pkg/ -> /pkgs/
- Add missing mkdir -p /build before makeself
- Mount pkgs directory via podman build -v so static.installer can access
previously built static tarballs without relying on bind mounts relative
to the build context
- Register qemu-user-static binfmt handlers for cross-compilation
- Make --git-repo optional when using --setup
