bfd target lists

[Alan Modra]

If anyone has taken a close look at the list of targets printed by
say, objdump --help, when compiled with --enable-targets=all, you
may have noticed that the default target is mentioned twice.

This patch corrects the situation, but since this may affect gdb
I'd like some comment from the gdb camp before I commit the change.

	* targets.c (bfd_target_list): Don't return the default
	target twice.
