Due to build order, WebKit on Symbian is building without Bearer Manager.
To fix this, we should replace the check for QtBearer.lib with the right CONFIG.
I think the best fix would be to enable the feature if one of the following two conditions is true:
1) We're building against Qt >= 4.7 - that check exists in the trunk right now.
2) $$[QT_INSTALL_DATA]/mkspecs/features/mobility.prf exists
Both options are platform independent and do not rely on symbian specifics.
An alternative way was found.
