[edk2-devel] [edk2-platforms][PATCH v2 2/7] Platform/Sgi: add no-stack-protector flag for StMM builds

["Prabin CA" <prabin.ca@arm.com>]

Add the no-stack-protector compiler flag to allow StandaloneMM builds
on both AArch64 and x86 host. Without this flag, the link stage fails
with the following errors on multiple files when built with gcc
(Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0:

undefined reference to `__stack_chk_guard'
undefined reference to `__stack_chk_fail'
