[RFC][PATCH] Makefile: Fix checkstack.pl arm64 wrong or unknown architecture

The following error occurs for the `make ARCH=arm64 checkstack` case:

aarch64-linux-gnu-objdump -d vmlinux $(find . -name '*.ko') | \
perl ./scripts/checkstack.pl arm64
wrong or unknown architecture "arm64"

Fix the above error by setting `CHECKSTACK_ARCH := aarch64` for the
ARCH=arm64 case.
