commit r14-6945-gc659dd8bfb55e02a1b97407c1c28f7a0e8f7f09b

Implement ASM_DECLARE_FUNCTION_NAME using ASM_OUTPUT_FUNCTION_LABEL
gccint recommends using ASM_OUTPUT_FUNCTION_LABEL in
ASM_DECLARE_FUNCTION_NAME, but many implementations use
ASM_OUTPUT_LABEL instead. It's inconsistent and prevents changes to
ASM_OUTPUT_FUNCTION_LABEL from affecting the respective targets.
