... because I am trying to test the universal build right now on a 64bit 
system, and my first attempt to circumvent the 64bit build *) failed apparently 
the `-arch i386` flags set by the macx-clang-32 spec got lost on most 
components of libQt5Bootstrap.a
*) `port configure qt5-mac-devel +universal` followed by `(cd `port work 
qt5-mac-devel`/build-i386; wmake --MP)` with wmake just a script that applies 
the same environment as MacPorts does. 

You were right, the universal arch. build order is determined in macports.conf, 
but so far doing things "correctly" using `port build` leads to the same error.
