# DP: - When building the native gnat, link the gnat tools against
# DP:   the build tree (build/$(host_alias)/{libgnatvsn,libgnatprj}.)
# DP: - When building a cross gnat, link against the libgnatvsn-6-dev
# DP:   and libgnatprj-6-dev packages.
# DP:   This link will be done by /usr/bin/$(host_alias)-gnat*, thus
# DP:   the native gnat with the same major version will be required.
