Configure options I use (configuration seems to work fine, no errors):

bq. -debug-and-release -opensource -confirm-license -opengl desktop -nomake demos -nomake examples -nomake tests

make command (dah): mingw32-make

any help to how to resolve this will be much grateful!

edit1: I did some more research and it's seems to be something related to OpenGL, but nothing on how to resolve this.

edit2: I configure with -no-opengl and run mingw32-make, got the same error so, need more ides here.

edit 3: if I change this line

_control87(oldbits, _MCW_EM|_MCW_DN|_MCW_RC);

in qlocale_tools.cpp to

_control87(oldbits, MCW_EM);

it's run until I get this error:

c:/mingw/bin/../lib/gcc/x86_64-w64-mingw32/4.7.2/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lQt5Cored0

That was due to a bug in Qt's source code itself. It has been fixed now; fetch the latest code from Git

Damm! I was trying so many times to build Qt5 with mingw-builds and failed. By the way I have succeed doing so with VS2012 command prompt, but since I didn't like all the include changes, and I'm working with a shared project with someone who have Qt4.8.x, I have decided to build Qt4.8.x and QtCreator with mingw-builds which worked great (a 64bit build).
Nevertheless thanks a lots, when I finish working on the shared project I will try to build Qt5 again.

Yeah, the bug sneaked into the Git repo because the developer tested it on MSVS, but didn't realize that MinGW behaved differently.

The include changes were to make it easier to manage Qt, and easier to introduce new features.

Good luck with your shared project, and with testing Qt 5 in the future!
