    crossgcc: Preparations for building Ada frontend
    
    As with most other languages, a pre-installed Ada toolchain is needed
    to build gcc's Ada frontend. To support building with older host tool-
    chains, the patch `gcc-5.2.0_gnat.patch` disables warnings for unknown
    pragmas. Building has been tested with host gcc-4.9 and hopefully works
    with newer versions, too.
    
    For convenience, the gnattools (e.g. gnatmake etc.) will be build if
    'ada' is specified as a target language.
