+	* elf/tls-macros.h (__TLS_CALL_CLOBBERS <__powerpc__>): Remove r3.
+	Define and use for __powerpc64__ too.
+	(TLS_LD <__powerpc__>): Add r3 to clobbers.
+	(TLS_GD <__powerpc__>): Set asm output.  Make __result r3 reg.
+	(TLS_GD <__powerpc64__>): Make __result r3 reg.
+	(TLS_IE <__powerpc64__>): Relax output constraint.
