build: Use -ffreestanding
this is a stand-alone/baremetal application, therefore demanding -ffreestanding would help it compile with hosted toolchains e.g. ( linux toolchains ), it also ensures that it won't be using platform optimizations like inlining mem* str* functions which gcc might decide especially with wrapper string functions in opensbi code Signed-off-by: Khem Raj <raj.khem@gmail.com> Reviewed-by: Anup Patel <anup.patel@wdc.com>
