Is it possible/planned/impossible to move the changes to Cygnus
configure to binutils and gdb as well (and then possibly even
autoconfiscate them at the same time, dumping Cygnus
configure at last)?

This would introduce the autogen dependency on binutils and
gdb as well... could it be an idea to rewrite Makefile.tpl in m4?
It does not seem to use advanced autogen constructs.
