Build core2 (i686) U-Boot for a core-i7 (amd64) image
On edison U-Boot is 32 bit. I'm building a 64 bit kernel + rootfs.
The only recipy that fails is U-Boot with:
undefined reference to `__normal___udivdi3'
Apparently, when building 32 bit U-Boot outside of yocto on a 64bit machine you need to install gcc-6-multilib.
How would I configure poke or change the recipe to do the same?

this means gcc is generating a helper call which it assumes libgcc will provide but here the toolchain in multilib env might be not providing it.
One solution is to rewrite the code such that this call is not generated by gcc. So help the compiler.

I am not using multilib yet, as I don't know exactly how to do that. Actually that is my question.

Rewrite U-Boot to not use this helper, that doesn't sound right.
I would rather tell this specific recipe to use the 32 bit compiler, while all other recipies are built with 64.
