The NIS or icecc can't work when task network is dissable, add BB_TASK_NETWORK
to enable network globally for such exceptions.
Note, enable nscd on the build machine might be a solution, but that isn't
reliable since it depends on whether the network function has been cached or
not.

As Quentin mentions, I'd much rather this was done on the tasks using icecc
using the flag.

I think we should move this code into bitbake as I really dislike having it in
bitbake.conf and that [0][1] syntax is horrible too...
I'm also not convinced about the name "BB_TASK_NETWORK" and think we need
something better. If we're moving the code to bitbake we might not need a name
right now though.
Yes, it's enough for NIS without a name, it seems that NIS is the only case atm,
I will send a V2 about this.
