[yocto] problems adding extra packages

[Jim Abernathy]

In the past on denzil, I'd get images working then start adding specific 
packages like this:

LICENSE_FLAGS_WHITELIST = "commercial"
CORE_IMAGE_EXTRA_INSTALL ?= "gst-fluendo-mp3"
CORE_IMAGE_EXTRA_INSTALL ?= "web-webkit"
CORE_IMAGE_EXTRA_INSTALL ?= "myvideos"
CORE_IMAGE_EXTRA_INSTALL ?= "myaudios"

Today, I got chiefriver bsp working on my hardware and then wanted to 
add my video and audio files into the image along with extra software.  
It didn't get added and the image is basically the same size. No errors 
on just bitbaking again.  I was trying to avoid deleting tmp and 
starting over again.  Has something changed with Danny?

Along with the CORE_IMAGE_EXTRA_INSTALL additions, I added my layer in 
bblayer.conf to pick up myvideos, etc.
