      6 # To support the Sun linker we need to make it behave like the GNU linker
      7 # for orphaned sections.  That means generating __start/__stop symbols
      8 # for them and that means some nopoly-atheist-withoutfood level trickery.
      9 # We enumerate all the section names we wish to generate symbols for.
     10 # The good news is that it's unlikely for NetBSD to grow any more
     11 # link sets, and even if it does, it'll be a build-time failure
     12 # on Sun platforms so it's easy to catch and mend the list below.
