I thought we passed /DYNAMICBASE:NO directly , but I don't see that in
the code. A look at the git logs shows that we disabled it in
7f3e17b48 by emitting
<RandomizedBaseAddress>false</RandomizedBaseAddress> in the MSBuild
project. That'll pass /DYNAMICBASE:NO to the linker.

It's rather better than the old registry hack, but it's a compat
option we're likely to lose at some point.
