Patch 1/3 the busybox change.  I'm not sure we really want to make that change 
as it will increase the size of busybox.

(following is me thinking aloud and hopefully someone will have a suggest on how 
best to unify this..)

I'm wondering if instead of forcing the change for everyone via the busybox 
change, if it makes sense to add a image validation routine or something that 
verifies if the DOC_COMPRESS is set, that the corresponding tool was installed 
into the target environment (along w/ man, info or other appropriate items.. and 
the pkgs-docs was set as well.. if any of those are missing then a warning 
should probably be presented.)

I'm sure there is probably a better way to set this via a distribution 
configuration switch or something as well.. maybe something like?

DISTRO += "man info"

That could then force the man and info systems to add a dependency on bz2 (or xz 
or whatever else was set in DOC_COMPRESS)..  and also add man, info and the 
associated man and info pages to the image itself.

(As I see it, DOC_COMPRESS is really a distribution wide setting, so we should 
treat it as such...)
