This is usually not how it's done.

Place your source directory next to a build32 and build64 directory. 
qmake have supported srcdir != builddir for many years, and it pretty 
much solves the problem.

Like this:

project_dir
   sourcetree (in svn, git or whatever)
   build32
   build64

cd to build32 and run

"QMAKESPEC=linux-g++-32 qmake ../sourcetree/myproject.pro".

Same for 64 bit.

You can even make a small makefile that builds both at the same time if 
you want to.
