2.6.15 make fails with multiple targets in parallel

[Keith Owens]

Running make on the kernel tree with multiple targets on the command
line and in parallel mode gets errors.  The prepare targets are run
several times, once for each target on the command line.  Sometimes the
result is sensible, sometimes the prepare commands overwrite each other
with either garbage or missing files.

I know that the command above is equivalent to 'make -j12' but that is
irrelevant, make is supposed to handle multiple targets without
repeating commands.

Is this where we mention http://www.google.com/search?q=cache:HwuX7YF2uBIJ:aegis.sourceforge.net/auug97.pdf&hl=en ?
