Hi Sterling,
the last thread pointer builtin changes left an unused 'arg' variable in
xtensa_expand_builtin(), which triggered a new warning. Thanks to
Jan-Benedict for testing this. Attached patch was committed as obvious.

Thanks,
Chung-Lin

	* config/xtensa/xtensa.c (xtensa_expand_builtin): Remove unused
	'arg' variable.
