Again, I don't really understand what you're asking.  It seems like you
want to automatically expand or contract the number of jobs that make
will run in parallel, based on some processing of the recipe.  For
example, if you start make with -j4 and a given recipe make invokes uses
2 cores, then make would understand this and count the job as using 2
"slots" in the jobserver instead of one.

This is not possible today, and I don't see any straightforward way to
do it.
