In general, we should be looking to be OS-agnostic via abstractions
like this, and so I'm all for it...

Your patch only includes a diff for - we usually put these
fields in every platform .mk file, so that it's easier to compare and
contrast between platforms, and so that we can use the files as
templates.  Whilst it may seem like redundancy in some of the other
platform .mk files (or even a duh-like stating of the obvious), it's
much easier if each file contains the information.
Thanks, this looks great!
