Does that mean the patch is OK or do you want me to get rid of the use
of $(shell) as Roland suggested? If so, I need some help because I
don't know how to rewrite this patch to make it use a generated Makefile
instead. I am not sure what Makefile/configure script would generate
the Makefile, what targets the Makefile would have or where the
generated Makefile would be included from.
