You might end up surprising people who have installed from source for
years and will have the layout suddenly changed, especially on RedHat
flavored systems.

I can work around it in the buildfarm, which does make some assumptions
about the layout (e.g. in the cross version pg_upgrade stuff), by
explicitly using --libdir.
