Configure with win32-g++ fails with idc

Configuring 4.8.0-RC fails with the following options:

configure -debug -no-ltcg -commercial -static -platform win32-g++ -xplatform win32-g++ -no-iwmmxt -no-crt -fast -opengl desktop -no-openvg -no-exceptions -no-accessibility -no-qt3support -no-rtti -no-stl -no-dsp -no-vcproj -no-incredibuild-xge -qmake -process -no-xmlpatterns -no-multimedia -no-audio-backend -no-phonon -no-phonon-backend -no-webkit -no-script -no-scripttools -no-declarative -no-declarative-debug -no-3dnow -no-sse -no-sse2 -qt-style-windowsxp -qt-style-windowsvista -no-libtiff -qt-libpng -qt-libmng -qt-libjpeg -nomake tools -nomake examples -nomake demos

It will give the following error:
mingw32/bin/ld.exe: cannot find -lQtGuid
collect2: ld returned 1 exit status
mingw32-make[2]: *** [..\..\..\bin\idc.exe] Error 1
mingw32-make[2]: Leaving directory `D:/qt4.8.0_rc/src/tools/idc'
mingw32-make[1]: *** [debug] Error 2

idc should not be included for MinGW.

This patch will fix the issue:
