Pull up revision 1.21 (requested by mycroft):
  Fix two problems:
   o Do not generate invalid PLT slots under `-Bsymbolic'.
   o Do not prebind GOT and PLT slots when `-r' is used; only do so
     if `-Bsymbolic' is used.  This avoids inadvertent prebinding of
     symbols when using `-r' with PIC files, which would otherwise
     make it impossible for an executable to override the symbols
     from a shared library.
  Also a few code cleanups.
