[PATCH 21/22] [GDBserver] Multi-process + multi-arch: LynxOS

[Pedro Alves <palves@redhat.com>]

This adjusts the LynxOS ports to new interfaces.

Completely untested.

2012-05-29  Pedro Alves  <palves@redhat.com>

	* lynx-i386-low.c (tdesc_i386): Declare global.
	(lynx_i386_arch_setup): Set `lynx_tdesc'.
	* lynx-low.c (lynx_tdesc): New global.
	(lynx_add_process): Set the new process'es tdesc.
	* lynx-low.h (struct target_desc): Forward declare.
	(lynx_tdesc): Declare global.
	* lynx-ppc-low.c (tdesc_powerpc_32): Declare global.
	(lynx_ppc_arch_setup): Set `lynx_tdesc'.
