Macros STACK_FRAME_NON_STANDARD and ANNOTATE_NOENDBR uses _ASM_PTR. It switch between .long and .quad based on 32bit or 64bit. However objtool doesn't work for 32bit, so _ASM_PTR makes no sense.
Considering that _ASM_PTR comes from asm.h, which is x86 specific head file, while objtool.h is generic. Replace _ASM_PTR with quad and remove asm.h reference.
