Remove FORTIFY_SOURCE since it is not compatible with or used by musl libc. Switch stack protector from all to strong since strong covers the entire practical stack smashing protection threat model. Switch -ftrivial-auto-var-init from pattern to zero since it is no longer being removed from Clang and is more suitable for hardening. Sort compiler flags A-Z.
