When current-processor-count is used without (ice-9 threads) being used, Guile
complains with the following warning:

Detecting when no files were installed was broken when switching to use
cond. Test with (not (null? ...)) to fix this.
* guix/build/emacs-build-system.scm (install): Fix detecting when no files
were installed.
Modify the install phase to detect when nothing has been installed, and error
if this happens. This is preferable to continuing, and allowing the next phase
to fail.
Also, when nothing can be found to be installed, print out each file that was
considered, along with the regular expressions that were used to include and
exclude it.

checking and logging.
