Move these variables over to the shared.max, we'll make use of them in a subsequent commit. There was no reason for these to be "simply expanded variables", so let's use the normal lazy "=" assignment here. See 425ca6710b2 (Makefile: allow combining UBSan with other sanitizers, 2017-07-15) for the commit that introduced these.
