Generates a zero-byte file which is promptly deleted.  So this file is
never generated.

Oh. I see.  I had misunderstood the rule:
$(addprefix $(srcdir)/,$(MKFILES)): %.mk: %.rmk genmk.rb

as being a generic rule.  I'll try to send a patch for that as well. 
Adding it to RMKFILES also helped.

Do you accept GNU make-isms, or are you restricting yourself to POSIX
make?
