Hi all,

I've a list of targets each in a different directory that was built and
now I want to clean them up. Each directory has a own "clean" make
target, so I wrote in the base directory makefile:

for MODULE in $(MODULE_LIST); do make -C $$MODULE clean; done

But this iterates only module by module and does not allow any jobserver
operation via "+ make".

I would like to make clean in parallel because there is not only
deleting of files in it but a bit more so it can be really parallelized.

A similar problem appears in if - statements they are all within the
same commandline and cannot be handled via "+ make" and the jobserver.

'clean' target usually removes files. If your fs is not on RAID
it  is scarcely probable getting speedup with parallel build.
