    Fix bootstrap tools build on macOS after 02af91c52e71e8a0f47251e637c9687f35d45dd9
    
    After changing the namespace.h header we need to provide _err on macOS, too.
    Previously we used the system libc err*/warn*, but that does not provide
    _err/_warn (which is used by other bootstrapped files from libc).
    To fix this problem bootstrap err.c on macOS as well.
    
    Fixes:          02af91c52 (Fix crossbuild bootstrap tools build with Clang 12)
