[patch ada] Use Ada output of gnatbind for building tools

[Tristan Gingold <gingold at adacore dot com>]

Hi,

gnatbind can generate Ada or C output.  The C output is being deprecated so it shouldn't be used to build the tools.
This patch updates the Makefiles so that the Ada output is used instead.

Ok for trunk ?

Tristan.
