Subject: [PATCH] Makefile: disable stack protection

The Buildroot toolchain might enable stack protection by default. That
breaks linking because ATF does not provide the required __stack_chk
routines.

The mv-ddr-marvell Makefile provides no way to add custom CFLAGS. Patch
Makefile to disable stack protection.

Upstream: not applicable; Buildroot specific
