This attempts to provide a nicer error message for the subset of users who build their own kernels without COMPAT_FREEBSD11 and then attempt to build lang/rust. The Rust ecosystem currently uses pre-ino64 syscalls, so building lang/rust without COMPAT_FREEBSD11 is not going to work. The error message for this is non-obvious and there is a new bug for this at least every 1-2 months. Hopefully this will improve the situation a little. Cargo and Gecko ports are similarly affected, so add the pre-build check to them too.
