packages/autoconf/autoconf-native: Do not RRECOMMEND automake-native
    For the native case do not ask BitBake to build automake-native,
    packages that need automake can DEPEND on it directly. This avoids
    circular depenendencies as autoconf-native would ask for automake-native
    and automake-native would ask for autoconf-native again.
    This 'fix' (I think it is proper) avoids build errors on  broken
    debian systems. And making OpenEmbedded independant of the host
    once again.
