bc is not in linux-source debs.Recommended, neither in Documentation/Changes

[Regid Ichira <regid23@nt1.in>]

  I didn't get response for a similar post on 
http://lists.debian.org/debian-kernel/2013/06/msg01262.html.  Is it 
because the answers are too obvious?

  bc, an arbitrary precision calculator language, is a kernel build
dependency since a long time ago.  Should it be added to:

    1. The Recommends field of linux-source-(version) debs.
    2. Compilation section of kernel-source:Documentation/Changes.

?

issue in Gentoo.
