I tried a more explicit aproach, addition |macx-clang-32 though evidently your suggestion should have the same effect.

But that just exposes another issue. The gyp generator insists on adding a -Dtarget_arch=x64 option, but in the end the ninja.build file is the only one that is configured correctly for building 32bit on a 64bit platform. Apparently I keep running into an issue where qmake ignores the mkspec file for everything inside the Qt 5.4 source tree. Unless it is called through (or as a direct consequence) of invoking `configure -platform i386`.

In other words, it seems I cannot do a "cross-bit-length" build of individual Qt components using an already configured and installed QtBase, not even in a fresh working copy of the source tree.
