I think one of the goals of ‘guix build -S’ is that you can take the
source and build it *on GuixSD* with hopefully few additional
modifications.

>From that perspective, the “hacks” are really fixes or workarounds
(/sbin/ldconfig doesn’t exist on GuixSD.)

Now, granted, there are inelegant workarounds that we’d rather hide;
these two may well fall into this category, so I’m fine with moving them
to a build phase.  Ricardo?

Still, it’s not obvious to me where to draw the line in the
general case.
