#
# Generate PVM architecture string.
#
# This is a heuristic thing that may need to be tuned from time
# to time.  I don't know of a real solution to determining the
# machine type.
#
# Notes:
#   1. Local people mess with things.
#   2. It's good to try a few things for robustness.
#   3. Don't use test -x
