[oe] Missing or unbuildable dependency chain when machine == qemux86 and distro == minimal

[Guo Hongruan]

Hi guys,
   I met the following error when building base-image. So I think it is  
better to remove the ANGSTROM_FEED_CONFIGS reference in base-image.bb, so  
that it is distro-independent.

bitbake base-image

Missing or unbuildable dependency chain was: ['base-image',
