nto-procfs.c: Add "target native".

Browse Source 
This makes QNX/NTO end up with two targets.  It preserves "target
procfs <node>", and adds a "native" target to be like other native
ports.

Not tested.

2014-05-21  Pedro Alves  <palves@redhat.com>

	* nto-procfs.c (procfs_can_run): New function.
	(nto_procfs_ops): New global.
	(init_procfs_targets): New, based on procfs_target.  Install
	"target native" in addition to "target procfs".
	(_initialize_procfs): Call init_procfs_targets instead of adding
	the target here.
