The only way to do this with the current version of GNU make is to use
dynamically constructed makefiles, combined with GNU make's auto-re-exec
capability.

That is, include a makefile:

  include generated.mk

but don't create generated.mk yourself, instead write a make rule that
generates it:

  generated.mk: Makefile
        rm -f $@
        for f in $(filter cfgtfr_%.c,$(ALL_FILES)); do \
          echo $$f : `echo $$f | sed 's/^cfgtfr/cfg/'` >> $@; \
        done

Done.
