We used to have bc in our list of required host packages in the Yocto Project 
quick start guide, but after some testing a few versions ago I removed it 
because it didn't seem to be needed. FWIW I don't have it installed on my 
primary build machine and I haven't noticed any problems as a result.

Rather than creating bc-native I think we should find out where the dependency 
on bc exists and try to patch it out (if practical); if it really is needed 
and too hard to remove, we can just add bc to the list of required host 
packages. I hope that's not the case though.

Cheers,
Paul
