Matt,

That is fine - if you want to base your work on an official release, you 
should stick to AMSDK 7.0 config. I thought you were trying to get the latest 
code pulled in, which would be a different approach.

AMSDK 7.0 was based on Dylan, which is now 3 versions behind the latest Yocto 
Project release. It was validated on Ubuntu 12.04 (and 10.04), so it may have 
incompatibility issues with newer Linux distros, like you found out. This is a 
more generic issue - the wider the time gap between the versions of the tools 
being used (e.g. Linux host distro, cross toolchain, etc) and the components 
being built (e.g. kernel, bootloader, user space apps, etc), the higher 
chances are for extra issues, breakage and other weird problems...
