   How would this work?  If the option were supplied would I append
   remote-qnx.o to TDEPFILES?

You can add to the various CONFIG_ variables, e.g. you would add
remote-nto.o to CONFIG_OBS.  See how the CLI, MI, TUI etc. are handled
in configure.in.

Anyway, I don't consider the fact that remote-nto.o is listed in
TDEPFILES a problem, as long as the *nto-tdep.c files don't depend on
it.

   The missing tm-qnxnto.h was an oversight - not necessary for the question I
   was asking.  The tm-nto.h file is necessary because configure will not build
   a native debugger without it, even if it's empty.

Huh?  Are you saying that, even though you don't mention tm-nto.h in
any of the Makefile-fragments you're adding, you need the file to
build GDB?

   I'm trying to solve a few annoying bugs (SOLIB_BKPT_NAME and
   SVR$_EXEC_EMU) first before I submit.

Fair enough.  I'm just looking forward to the end-result.
