           Summary: Qt's qmake uses wrong pkg-config

Creating a toolchain for ARM with the latest Qt library will install it's
libraries and QMAKESPECs. Theses QMAKESPECs have the CXXFLAGS and the correct
compiler, but don't address the pkg-config location.

If using pkg-config with qmake, it calls pkg-config from /usr/bin which causes
wrong include dirs.


########## Example ##########

Write to your *.pro file:

    # see
http://doc.trolltech.com/4.6/qmake-project-files.html#configuration-features
    CONFIG    += link_pkgconfig
    PKGCONFIG += fuse


If the wrong pkg-config is used, the include directory points to
"-I/usr/include/fuse" - otherwise to a directory inside your toolchain.

I'm using buildroot 2011.08 with the CodeSoucery 2009q1 toolchain.
