Ah, ok. Will do -- thanks!

Where did I do that?

-r, --no-builtin-rules
Eliminate use of the built-in implicit rules. Also clear
out the default list of suffixes for suffix rules.
There isn't a way to disable -r in make-3.81 except by removing it
from MAKEOPTS (that's how it was enabled in our make system at Cisco
in my group). `MAKEOPTS=;' is the quick way out. Nasty PITA...

I only did that to ensure that this commit could go in, irrespective
of PATCH 3/4, but I agree, it should be enabled once both changes are
committed.

ar [blah]
ranlib [blah]
maybe?
Thanks!
