[OE-core] [PATCH] qt: updated qmake2 class to export qconfig.pri mkspec

[eu at felipetonello.com]

From: "Felipe F. Tonello" <eu at felipetonello.com>

This is necessary when Qt applicatins want to know variables such as
QT_MAJOR_VERSION, QT_VERSION, QT_MINOR_VERSION, gcc version etc.

OBS: This change made the build system crazy. When I changed it and run
bitbake my-qt-app-recipe, qmake was consuming 100% cpu usage for long time. I
had to stop it. So I recommend rebuild the entire Qt stack when changing this.
