It would be cool if at parallel builds make exported a shell
variable whose value is a reasonably small integer that is
unique amongst the jobs running at the same time. For example
if I type "make -j10" then this would be a number from the 0..9

Rationale: we have a distributed build system where we build
packages of a complete Linux distribution. The actual build is
performed on several hosts, each one runs 1 build at a time.
The main server controls the whole procedure using a Makefile
set up based on the packages' build-time dependencies (loops
eliminated), and performing a "make -j <number_of_build_hosts>"
command to rebuild all the packages.

Currently we have some dirty tricks to find a free client that
does not run any build so is willing to accept the new one.
I think it wouldn't be too hard for make to tell this
explicitely, through the SLOT_NUMBER (or something else)
environment variable.
