That is probably not the best fix for the problem, but it doesn't make
it any worse.
It will allow proper images to be built until better fix is provided.

While you're at this, please look into recipe for 'bc'  tool, that is one
which causes problems. While speaking about busybox - it RRECOMMENDS
busybox-syslog which prevents normal syslog from being installed at
image build time.
I'm a bit afraid to touch this part to not break images for others,
probably some
"virtual/syslog" package is needed?

Thanks a lot,
