Undefined reference error while trying to build QStyledPlugin

Silencekeeper

I'm trying to build qstyledplugin from http://qt.gitorious.org/qt/qtstyleplugins using mingw-4.7.2 and Qt5.0.1 from http://qt-project.org/forums/viewthread/23002 but I get this error:

     bad reloc address 0x36 in section `.text$_ZN8QPainter8drawLineERK6QPointS2_[__ZN8QPainter8drawLineERK6QPointS2_]'

How can it be solved?

I have the same error when trying to build with official Qt 5.0.1 for Windows 32-bit (MinGW 4.7).
