Package capture in the presence of multiple make jobs outputting
to a common directory, typically, through a common part of the
build system infrastructure.

It goes back to a suggestion of mine a few months back in answer
to (one of many) posts about capturing the build output in
distinct packages.

Have been working on parts of my own suggestion and think I can
make it work, __IFF__ you run Buildroot -j1.

Which no one of sane mind, with a multicore machine will be 
interested in doing. ;-)

I did also consider dropping that restrictive phrase: "outputting
to a common directory" -
But that I consider both too invasive, and against my declared
intent to make it a transparent feature addition for the user.

Will continue giving my own suggestion more thought as time
becomes available.

After all, (on a failure) make does have that: "Waiting for xyz
jobs to complete" message, it does "know" how many jobs are
running at the moment.

But I certainly don't want to propose patching make to expose
the job identification if it doesn't already provide that.
