Thanks very much for taking the time to follow this up with the
make mailing list (and if you happen to post to that list again
you could pass on my thanks to Paul for looking into this as well).
I guess we should treat ARFLAGS the same way we do LDFLAGS
and friends -- capture the setting in configure (with a default of
"rv" if unset) and write it to config-host.mak. Then we'll be setting
it explicitly for our top level make which can pass it down correctly
to the dtc makefile.

I'll put together a patch...
