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.
