  58    may not.  If we are asked to compile position independent code, we
  59    always pass -k to the assembler.  If it doesn't recognize it, then
  60    it will barf, which probably means that it doesn't know how to
  61    assemble PIC code.  This is what we want, since otherwise tools
  62    may incorrectly assume we support PIC compilation even if the
  63    binutils can't.  */
