[PATCH 0/1] Cross-compiling 32-bit macOS from 64-bit-only macOS.

[Dean Greer]

> It seems to me that this should be done the same way we do it on Linux:
if we are on an x86_64 host and --enable-win64 is not specified, we add
-m32 and set host_cpu=i386. Passing --host is not required in this
configuration.

If the compile is being done via an Intel Mac that’s not required, when
compiling via an Apple Silicon Mac just launching the session via Rosetta2
will allow you to skip setting -m32 & host_cpu.
