[PATCH] Fix configure so rebuilds link against latest libs

[Lawrence Rust <lvr@…>]

When changes to mythtv library components affect the symbols exported, it is important that future re-builds use the correct -L paths to avoid linking with old libraries. This is most important if Qt and MythTV are installed with the same prefix. The mythtv configure script has some code to deal with this situation:

QMAKE_LIBDIR_QT-=${sysroot}${libdir}

This removes the extra-libs path from the front of the search path and later appends it to the end. However, with Qt 4.7.x (maybe others) the Qmake variable QMAKE_LIBDIR also affects the search order. The attached patch applies the same logic to that variable. The resulting Makefiles then have the correct path order for LIBS.
