Currently in oe-core there is no aarch32 tune support, there is only
aarch64. There have been patches proposed but nothing has been merged
yet.

You could use the meta-axxia implementation of aarch32. Adding the
layer and including the tunes it in your machine will give you the
tune options, then you can pick what you need.
(https://github.com/axxia/meta-axxia/tree/master/conf/machine/include)

Or you could use the meta-linaro layer implemention for ilp32.
(http://git.linaro.org/openembedded/meta-linaro.git/tree/meta-ilp32/conf/machine/include/arm64/arch-armv8.inc)

Also, if you were not aware you can have a multilib rootfs built with
OE. This would allow you to have the 64bit and 32bit arm libraries.
There is some documentation on it here:
