included) when using -j8 (about ~15s). And I understand your concern
about the complexity of the patch in the second solution.

parallelizing is just hiding dust under the carpet. The result after the
second solution is cleaner (to me): we get rid of an obscure shell
script and we stop piping make output to files thus restoring the
possibility to use make -d to debug problems.
And while the goal is to reduce the config time, why not go all the
