[PATCH 1/1] meson: Deprecate 32-bit host support |

We deprecated i686 system mode support for qemu 8.0.
However, to make real cleanups to TCG we need to remove
all 32-bit hosts.

+Keeping the 32-bit support alive is a substantial burden for the QEMU

+Recent testing on 32-bit host OS has been inadequate at best, apparently
