Being puzzled goes on. The log did not reveal much to me. A few
observations:
 * It actually does not use -nc (as you said) and really does run make
   distclean (as does the failing one).
 * make distclean does not run configure (unlike the failing one).

I added --debug=a to a local test build and this is what I get:

|         make -j8 distclean --debug=a

Once configure is invoked, things go bad.

>From what I see, GNUmakefile sets:

| GNUSTEP_LOCAL_ADDITIONAL_MAKEFILES=gui.make

and then does

| include $(GNUSTEP_MAKEFILES)/common.make

which comes from gnustep-make and does

| ifneq ($(GNUSTEP_LOCAL_ADDITIONAL_MAKEFILES),)
| include $(GNUSTEP_LOCAL_ADDITIONAL_MAKEFILES)
| endif

which is combined with GNUmakefile.postamble as included via

| include GNUmakefile.postamble

and contains

| gui.make: gui.make.in Version configure
|         if [ -x config.status ]; then \
|           ./config.status --recheck && ./config.status; \
|         else \
|           ./configure; \
|         fi

and thus remakes gui.make as it does not exist.

Would you happen to see where this chain of logic fails for your build
and why it ends up not remaking gui.make? Consider adding --debug=a to
your make distclean invocation and comparing (or giving me the output to
compare).

Thanks for bearing with me.
