scons: Workaround failures with MSVC when using SCons 3.0.[2-4].

This change applies the workaround suggested by Bill Deegan on the
affected SCons versions.

It also adds a comment with the URL explaining why we were using
customizing the decider and max_drift in the first place, as I had
forgotten all about it.
