I guess this can be done equally well in a later patch. I don't really
like this workaround either, but it improves the current situation
surprisingly well.

I won't have the time to work on either improving chrpath or integrating
patchelf. If Khem has a working solution, then let's integrate it.

AFAIR, the reasoning against patchelf was the bad availability across
distributions and it being a prerequisite for native builds. Today,
there's still no patchelf package in current releases of Debian or Ubuntu.
