Add option for "timeless" builds
Builds with BUILD_TIMELESS=1 shall always give a bit identical output
for stable inputs. This should help verifying that resulting rom files
stay the same across commits that shouldn't change the outcome.
To be useful for builds that rely on 3rdparty/arm-trusted-firmware,
this needs a similar change there.
