Add support for aarch32 cross build in meson and add aarch64 -> aarch32 cross build to Travis.
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. v4: Removed disabled drivers which actually build on arm32. Also tested the patchset with series 9609 which fixes underlying failures. v5: Changed the condition for running test-null.sh in ci. Re-uploaded after underlying fixes have been committed. v6: Changed the condition for running test-null.sh again. Reworked the patch to do aarch32 build instead of arvm7-a build. Simplified meson build flags. Changed commit msgs. Added 32b qualifier to .travis.yml. Added a patch with fixes for bnxt. Added a patch with cross compilation docs. v7: Rebased the patchset. v8: Removed Makefile additions from net/bnxt patch. v9: Changed ci test-null.sh condition, only run it if not cross-compiling aarch64 nor aarch32. Cleaned up docs. v10: Fixed doc: add aarch32 build guidance commit message. v11: Rebase and fix scf and bnxt after rebase. v12: Dropped one superfluous net/bnxt patch. v13: Rebased and fixed net/virtio build by removing NEON for aarch32. v14: Fixed docs build. v15: Rebased. v16: Updated arm CPU flags. v17: Fixed build condition in 1/8, updated 4/8.
