Using shell wrapper for descrambling parallel make output

[Atte Peltomäki]

Hi,

As you know, running parallel builds with '-jX' makes the shell output
difficult to read, since output from parallel jobs are mixed. To remedy
this, the use of a buffering shell wrapper has been suggested:

I liked the idea, but implementation was lacking so I rewrote the
wrapper.

To further descramble output, upgrade to make 3.82 and use .ONESHELL:
directive. For doing this with the wrapper, a simple patch needs to be
applied to make so it treats the wrapper as a normal shell. I also
strongly encourage applying this patch for 3.82 which fixes a nasty
memory leak/corruption:

If I have time and interest, I will look into implementing the wrapper
functionality into make itself. Don't hold your breath, though.
