I may have been mistaken about the original source - it looks like I
used a similar module strategy from meta-freescale.  I did [just now]
try using "inherit module" and the build dies a horrible death with
this error
| make: *** No rule to make target 'modules_install'.  Stop.

I changed my [task] dependencies to match what you've quoted and everything
works as before.  !Thanks!
