ecpg.patch (wrong makefile expansion in some cases)

the ecpg Makefiles use a variable DESTDIR which is never defined
        except by debian/rules makefile, in which case the ecpg makefiles
        expand wrong pathnames. If we want to support a DESTDIR root it
        must be done consistently in all the makefiles, not just in ecpg.
