	Support for PowerPC NetWare.
	* config.bfd (powerpc-*-netware*): New target; use ppc-nlm.
	* config/ppc-nlm.mt: New file.
	* configure.in (nlm32_powerpc_vec): New target vector; use
	nlm32-powerpc.o, nlm32.o, nlm.o.
	* targets.c (nlm32_powerpc_vec): Declare.
	* Makefile.in (BFD32_BACKENDS): Add nlm32-powerpc.o.
	(CFILES): Should add nlm32-powerpc.c, but didn't, because the
	dependencies can't be sanitized.
