[yocto] unnecessary build of bzip2 when it's "required" for a dev host

[Robert P. J. Day]

  more nitpicking pedantry, but i just noticed that on the quick start
page, there is the standard list of what the developer must install
beforehand:

http://www.yoctoproject.org/docs/1.8/yocto-project-qs/yocto-project-qs.html#yp-resources

and for both fedora and centos, the reader is instructed to install
(among other things) bzip2. but i'm pretty sure bzip2 is compiled as
part of the build tools as part of a standard build, no?

  certainly, as part of my poky-based BBB, i can see
tmp/work/x86_64-linux/bzip2-native/. not a big deal, of course, but
apparently redundant. didn't bother checking if this is the case for
anything else.
