Please have a look at the commit message of Patch 1 of my RFC I sent a 
while ago:

[PATCH 1/5] rootfs: Do not recursively deploy every dependent package

which I have now rephrased as "rootfs: Do not recursively build unneeded 
packages".

I think it's very likely that you're hit by the exact problem i describe 
there.

Later in the RFC i have suggested to drop the optimization part of this 
patch. Having reworked the series since, it's possible to even keep it. 
If you want, I can send the reworked version.

regards,
Andreas
