##### ARM Hack ####
# Flex library linking went missing during 'Big Merge'.  This hack needs to be removed
# upon the next update/rebuild to find out why, as it worked fine prior to that event.
# Work around a missing link flag on ARM:
# Not the fix I have here, but it's a known issue with flex and for motif it happens
# during the configure phase, I *think* though due to the same reason here -
