  Add support for aarch32 cross build in meson.

Aarch32 is an execution state that allows execution of 32-bit code on
armv8 machines. This execution state contains a superset of previous
armv7 32-bit instructions and features. Thus the aarch32 build is distinct
from arvm7 build.

v18:
Rebased, adjusted to use arm soc format.

Acked-by: Aaron Conole <aconole@redhat.com>
