Nico Huber 135ca51314 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.
