I just ran into problems with the cross compile though, but I think
it is just a bad configure script. This patch should hack it to work.
If it detects that you are cross-compiling it doesn't even attempt to
look for the IEEE math stuff.

It also tries to do some perl stuff and I pull this out of the Makefile
with this.
	perl -i -p -e "s,^all-local:.*,,g;" $(RRD_DIR)/Makefile
