Forgive me if this is obvious, but: it's ok if your debug build is a
universal binary also.  Yes it increases your build time (which granted
could be long) but it's quite valid to have universal debug versions.

Also, don't use -m32, -arch is the correct way.

What you need is a way to have different values of
CMAKE_OSX_ARCHITECTURES in Debug and Release.  If CMake doesn't support
this, it would make a good feature request.
