Hi Victor,

You might want to have a look at how building Qt works in 
mingw-cross-env, even though this project cross builds only 32-bit 
static libraries.

It uses the makespec 'unsupported/win32-g++-cross' in the Qt source tree.

The configure recipe is here:
http://hg.savannah.gnu.org/hgweb/mingw-cross-env/file/tip/src/qt.mk

Some mostly cherry-picked patches are here:
http://hg.savannah.gnu.org/hgweb/mingw-cross-env/file/tip/src/qt-1-cherrypicks.patch
