    Description

      Something changed which has caused qmake to produce relative paths in the Makefile for the dependencies in the Android NDK.

      When combined with Qt Creator's long shadow build directory names on Windows, this will almost always cause us to hit the system path length limitation, which will cause errors like this:

    10:20:27: Elapsed time: 00:01.

      The problem here is that while the file exists, the path 

      $$REALLY_LONG_INSTALL_PATH\..\..\..\..\..\..\..\android-ndk-r9c\sources\cxx-stl\gnu-libstdc++\4.8\libs\armeabi-v7a\include\bits\c++config.h

      becomes too long for the system, so the file can't be opened by mingw32-make.

      I think we should return to using absolute paths for the dependencies.
