memset patch:
memset: add none NEON version support for armv7-a/r:
test with __ARM_NEON__ disable:
boards/arm/qemu/qemu-armv7a/configs/nsh/
arch:use ARCH_64BIT to mark arch is support 64bit
no C code modify, only Kconfig modification. Only need compile pass and CT
pass.
memcpy: fix link failed when open kasan:
