You can't.


Your only option is to use GNU make's auto-re-exec feature to generate a
dynamic makefile: write a rule that generates a makefile containing the
information you need (so you have the full power of the shell to create
it).  Then include it:

  dynamic.mk: Makefile
          @rm -f $@
          @for f in $(TARGETS); do \
            echo "$$f : \$$($$f_SRCS)" >> $@; \
           done

  include dynamic.mk
