I’ve looked around and it looks like I need to adjust the tuning to be for armv7 instead of the default. However, when I set DEFAULTTUNE in the application recipe it does not compile the 32 bit cross compiler and bails out with a dependency error. Is there a system in place where we can adjust the tuning for a specific recipe?

infact multilib is the solution, its not limited to libraries. If multilib worked for your arch you would

bitbake lib32-<yourapp>
and it will bring in all needed dependencies + compile your app in 32bit mode or whatever the multilib warrants.

Question however is if combination that you are expecting is supported or not.
