   run with multi-arch enabled.  Not sure about much else as there
   appears to be an unrelated problem in the SOM symbol table reader
   causing GDB to lose line number information.  Since prior to this
   switch and a other recent tweaks, 64 bit PA hadn't been building
   for some months, this is probably the lesser of several evils.  */
