Carl Worth 40e584ecfc Makefile: Silence compiler errors during dependency generation.
We have a bootstrapping issue with our dependency generation. When the
Makefile.config doesn't exist yet, the complete compilation flags are
not yet available for passing to the compiler to generate the
dependencies.

But we don't have explicit rules to create these dependency files,
(just the implicit rule that is created by the -include), so we can't
control when make will attempt to create them.

We do have a dependency of the dependency files on Makefile.config, so
make should eventually call the compiler with the correct flags and
everything should be good. So in the meantime, silence any complaints.
