I don't really have a strong opinion about this and the fix I
implemented was suggested by jlam@, so I'll let you two battle it
out :)

One possible concern is that while pkg_rr enforces the "safe" order in
which to update packages, some random make replace here and there does
not. In other words, it is possible to build a package that does
not have unsafe_depends=YES, but where some of the dependencies used to
build it had unsafe_depends=YES. I think as a safety measure we should
make unsafe_depends=YES propagate to the package being built if any of
the dependencies were unsafe.

If that is done we can remove the unsafe_depends in the replace
target iff all of the dependencies are safe.
