Subject: wxMac: Fix build flags

Use the standard `ENV.m32` to force a 32-bit build now that Homebrew's
environment tools can work with Objective C flags.

Only specify `-arch` flags when building Python modules---this prevents Python
from trying to build for more architectures than it should.

Fixes #10348.
