FWIW, the current behavior of $(MFLAGS) and $(MAKEFLAGS) is used as a
feature in Automake-NG (my Automake fork that assumes the generated
makefiles will only be run by GNU make); see the comments about the
'am.make.is-running-with-option' macro in
<http://git.sv.gnu.org/cgit/automake.git/tree/lib/am/header-vars.mk?h=ng/master>
Changing it will probably break something there :-(

But maybe, are you willing to implement new macro(s) that makes is
easier to probe at runtime, from within the makefiles, the flags
passed to GNU make?  In that case, I'd be more than willing to adjust
Automake and/or Automake-NG to take advantage of that.
