[ Upstream commit d4c937c2a57bbba24790be6fe7a791456f5fbb60 ]
FORTIFY_SOURCE could detect various overflows at compile and run time. ARCH_HAS_FORTIFY_SOURCE means that the architecture can be built and run with CONFIG_FORTIFY_SOURCE. So select it in LoongArch.
See more about this feature from commit 6974f0c4555e285 ("include/linux/ string.h: add the option of fortified string.h functions").
