Just add an after-clean:: command at the end of your GNUmakefile. :-)
(often those commands are put in a GNUmakefile.postamble and then that
file is included, but you can also just add them at the end or your
GNUmakefile).

If it's just for a single file, just copy from this example that will 
remove the file 'MyFile' --


include $(GNUSTEP_MAKEFILES)/common.make

TOOL_NAME = WorldPeaceMaker
WorldPeaceMaker_OBJC_FILES = WorldPeaceMaker.m

include $(GNUSTEP_MAKEFILES)/tool.make

after-clean::
        -$(RM) MyFile


'after-clean' commands are executed after all the other clean operations.  
You can also have a 'before-clean' section if you want.

don't forget the TAB before the '-'.  It won't work without it, as make
uses it to know it's a rule.

the '::' in after-clean are because it's a special rule, you're adding to 
an existing rule (a normal rule would have ':').

the '-' before the command means that if MyFile does not exist, no error 
is generated.

the '$(RM)' expands to 'rm' or whatever the shell command to remove files
is.

This 'after-clean::' way of adding commands is considered part of the 
gnustep-make public API so it is fully supported. :-)

Sorry for being pedantic, I imagine you already know most of this :-),
anyway it's also for future reference/help.

Hope that helps, thanks!
