[PATCH 01/24] toplevel: Substitute GDCFLAGS instead of using CFLAGS

[Arsen Arsenović via Gcc-patches]

r14-2875-g1ed21e23d6d4da ("Use substituted GDCFLAGS") already
implemented this change, but only on the generated file rather than in
the template it is generated from.

ChangeLog:

        * Makefile.tpl: Substitute @GDCFLAGS@ instead of using
        $(CFLAGS).
