This is an interesting example and a useful demonstration of why the
image version isn't always that useful.  The software build number
covers *everything* that goes into the image, but the image version
number is just the version of the top-level image recipe.  If you bump
the version of eglibc your image version won't be increased.

There's nothing to stop you doing versioned images but as the version
doesn't represent anything beyond the image recipe version it's not as
useful as you'd think.
