`DISTRIB_*` read os-release under `CMAKE_SYSROOT`, so cross builds got the target distro from a host-oriented command, and a process-wide static froze the first result. Add a `FROM_SYSROOT <bool>` option and policy `CMP0221` to default to the host, parse per call, and scope `CMAKE_SYSROOT` so the fallback scripts follow the same choice. Fixes: #27640
