HOST_ARCH in is used only to set HOST_OSTYPE, which in turn
is used only to set default for the obj dir and TOOLDIR.  Since "uname
-p" is not defined in SUSv3, perhaps we should just stop using it, and
use HOST_MACHINE!=uname -m instead of HOST_ARCH!=uname -p.

If we really do need uname -p (on hosts that support it), then I think
both nd should be changed to check for "unknown" in
addition to checking for failure.
