You may want to restrict the extent of the env to the make (+ it's children)
rather than the whole bash script, with the following:
ROOT_PID="$$" make -f yourmakefile yourtarget

Thanks for the nudge in the right direction but...
... an easier way to make that happen is to introduce an initial bash script:
#!/bin/bash
export ROOT_PID=$$
make -f yourmakefile yourtarget
[This will set the bash script's PID into the env of all descendants (which is
good enough for our purposes here as the make process itself needn't be the
actual root)].

The environment is passed on to it's child processes by make, so if you can
find a way to push the pid of your make run into one then you're done.
a) Invoke make as follows:
tmpf=`mktemp`
TMPF="$tmpf" make -f yourmakefile yourtarget &
pid=$!
echo "$pid" > $tmpf
wait "$pid"
rm -f "$tmpf"
b) Inside yourmakefile:
export MAKE_PID := $(shell while [ ! -s "$(TMPF)" ]; do :; done; cat <
$(TMPF))
###
Now all child(s) of this make shall inherit the env $(MAKE_PID)

Subject: pgid of spawned processes
Hi,
Is it possible to get make to pass on its process group id to any children
processes it spawns?
[Please 'reply all' as I am not subscribed to this group].
Thanks!
