Qt self-compile fails (Linker error win32-msvc2012 using x86 Native Compiler on 64Bit Win7)

When configuring Qt for win32-msvc2012

configure -debug-and-release -opensource -platform win32-msvc2012 -opengl desktop -nomake examples -nomake tests

and running "nmake", the compilation breaks with the linker error:

----> using msvc x64 Cross compile Tool (64 Bit machine) works!
----> using -no-accessibility works, too!

Hint/possible reason: The wrong Windows Active Accessibility file (oleacc.dll) is chosen (on some machines, WinSxS-Problem?) when compiling for 32bits on a 64bit Win7-Intel machine.

Please fix!
