This results in om.tmac and om.tmac-u being installed.  We want only
om.tmac (not stripped) installed.  If om.tmac-u is removed from the
sources and replaced with om.tmac (unstripped), the attached patch
should give us what we want.

On the subject of strip.sed (which we don't want used on om.tmac),
even with Bjarni's suggested patches, it still removes the \" that
protects trailing spaces from constructions like

  .ds foo \
  bar \"
