I used it to run `make localmodconfig` in a linux build, others might
find it useful as well. Should I contribute it to the cookbook or Guix
itself as well?
```
(define (error-before phase pkg)
(package
(inherit pkg)
(arguments
(substitute-keyword-arguments
(package-arguments pkg)
((#:phases phases)
`(modify-phases ,phases
(add-before (quote ,phase) 'error-on-purpose
(lambda _
(error "error on purpose")))))))))
```
