    build: handle directory with whitespace in AUTOREMOVE clean
    
    Package with whitespace in their build directory are not correctly
    removed when CONFIG_AUTOREMOVE is enabled. This is caused by xargs that
    use whitespace as delimiters. To handle this use \0 as the delimiter and
    set find to use \0 as the delimiter.
