I poked with this a bit over the weekend, and never did get the right 
results.

I can make the scripts trigger, but since the sysroot population appears
to already be done, but build scripts don't actually make it into the
sysroot for use during module builds.

I tried a few variants of the below, all trying to get the actual
tmp/sysroots/<machine> to have the scripts, with no luck. Dumping the
available variables didn't get me anything really promising either.

I'll have another look in the morning, since I'm sure it is just me not
understanding the ordering of things .. but any pointers would of course
be appreciated.

Cheers,

Bruce
