BUILD_ARCHwithCMAKE_HOST_SYSTEM_PROCESSORand remove custom functionget_host_arch.I see no reason to not use CMake's variable for setting this, after all that is deciding what/how to build anyway. The custom function requires maintenance, macOS is currently not supported and defaults to
x86_64.The only effect this has is the
build_platformoutput ofg.version -g. Otherwise BUILD_ARCH is mainly a remnant of Autotools builds, where build output directory is named after Autotool's host variable (e.g.dist.aarch64-apple-darwin25.3.0; note: this is not the same as justuname -m) and this is passed to various Python build scripts, in CMake it doesn't play any role.
