dev-lang/gnat-gcc: version bump to 4.9.3 (ebuild and gnatboot)

Newly reworked gnat-gcc with new multilib and hardened support. Will
probably also need updates to gnat.eclass to build Ada packages.
Ncurses with use=ada works again (in the overlay) but the existing
gnat.eclass Ada configuration will most likely get simplified first.
Other arches still in progress.

Package-Manager: portage-2.2.28

+2013-08-22  Magnus Granberg <zorry@gentoo.org>
+
+	* gcc/gcc.c (main): Add support for external spec file via the GCC_SPECS env var
+	and move the process of the user specifed specs.
+
+    This allows us to easily control pie/ssp defaults with gcc-config profiles.
+    Original patch by Rob Holland
+    Extended to support multiple entries separated by ':' by Kevin F. Quinn
+    Modified to use getenv instead of poisoned GET_ENVIRONMENT by Ryan Hill
+    Modified to process the GCC_SPECS env var befor DRIVER_SELF_SPECS by Magnus Granberg
