is gcc-base-version.diff applied? I think we should build every cross build with
this patch.

gcc/BASE-VER now does omit the subminor version number. gcc/FULL-VER does have
it (used to print the version number for gcc --version).

Ludovic, please could you rebase gnat-4.6 to -15 and see if this works for gnat
as well?
