[ Upstream commit 4f45d62a52297b10ded963412a158685647ecdec ]
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"
As suggested by Masahiro Yamada, fix the above error using regular expressions in the same way it was fixed for the `ARCH=x86` case via commit fda9f9903be6 ("scripts/checkstack.pl: automatically handle 32-bit and 64-bit mode for ARCH=x86").
