Apparently that broke the installation, where part of the tools still
expect /gnu/store while others expect /home/felix/gnu/store.  You can’t
avoid running ‘make clean’ after such a change.

However, note that using a store other than /gnu/store will prevent use
of substitutes, which may be problematic on a slow machine.
