native/cross: Add ar wrapper for determinism

Add a wrapper around ar calls for native/cross recipes. This wrapper adds
the -D option so that deterministic archives are built for native/cross
output. This improves the changes of hash equivalence matches and hence
build artefact reuse.

We don't need this in the target case since we compile binutils-cross
with an option making this the default. We need a wrapper since we need
to remove the "u" option and replace it with "D" but also allow things like
"--version" to continue to work too.
