WIP: Run `makedepend` in parallel by using `make`
This moves the per-file loop body of `makedepend` into a separate
file named `makedepend_file` and then uses `make` to launch
the `makedepend_file` processes for each target potentially in parallel.
This reduces the time for
time sh ./makedepend MAKE=make cflags
from 5 seconds to 2 seconds with MAKEFLAGS=-j8
