Subject: [PATCH] FindQt4: do not prepend CMake root path when searching the
 mkspecs directory

When searching for the mkspecs directory, FindQT4 uses the find_path()
function, but it doesn't pass the NO_CMAKE_FIND_ROOT_PATH, which means
that all paths are interpreted relatively to the CMAKE_FIND_ROOT_PATH.

However, both the ${qt_mkspecs_dirs} and ${qt_cross_paths} variable
that are passed as hints are already absolute paths, and do not need
to be prepended by the CMAKE_FIND_ROOT_PATH.

Due to this problem, FindQT4 was unable to find qconfig.pri, and
QT_MKSPECS_DIR was left defined to "NOTFOUND".
