packages are normally built in /tmp, each package in its own subdirctory
guix-build-<package>. When interrupting the build with Ctrl-C, this
directory survives (and on most systems is deleted during the next reboot).

This looks like it is part of your successful upgrade of the system with
a substitute.
$ ls -l /var/guix/profiles
shows links to profiles in /gnu/store (and if space runs out, these can
be removed by deleting profiles and "guix gc").
