I think the complication starts before. :-)

Well, hoping to not misunderstand something or miss a point.

Currently, the tests are one among many other phases of the build
system.  Therefore, this would need to be extracted as a separated
derivation.  Somehow, there is 3 derivations involved when building a

 + fetch source
 + run build system
 + graft (optionally)

And somehow you would like to split “run build system” (./configure &&
make && make check)) as two derivations:

 + run build (./configure && make)
 + test (make check)

If we are here, we could make all the phases as separated derivations.
A corollary is that a failure about one phases step would not require to
redo all the previous steps.

Well, if my understanding is correct, separating the tests would be a
piece of work, I guess. :-)
