Machine: i386
>Description:
	see below.

	due to the way do_setshow_command() handles spaces,
	"NetBSD ELF" matches with both of "NetBSD a.out" and "NetBSD ELF".
	afaik, there's no way to specify one of them.
>How-To-Repeat:
	% gdb
	(gdb) set osabi
	Requires an argument. Valid arguments are auto, default, none, SVR4, DJGPP, NetWare, NetBSD a.out, NetBSD ELF.
	(gdb) set osabi NetBSD ELF
	Ambiguous item "NetBSD ELF".

 This is still broken in current's gdb 7 on amd64, although it's less
 obvious because "NetBSD a.out" isn't one of the choices.

 Plus maybe there's another problem:

 (gdb) set osabi NetBSD ELF
 warning: A handler for the OS ABI "NetBSD ELF" is not built into this configuration
 of GDB.  Attempting to continue with the default i386 settings.
 (gdb) 

 (gdb) set osabi NetBSD fail
 warning: A handler for the OS ABI "NetBSD ELF" is not built into this configuration
 of GDB.  Attempting to continue with the default i386 settings.
 (gdb) 

 I'm not sure to what extent this warning really matters.

 c.f. bin/49438 gdb complains it has no handler for OS ABI "NetBSD ELF"
