* config/qt4.m4
(QT4_FIND_PATH, QT_FIND_UIC4, QT_FIND_MOC4): remove,
AC_PATH_PROGS does this very well.
(QT4_DO_PKG_CONFIG): add $QT4DIR/lib to pkg-config search path;
do not run QT4_DO_MANUAL_CONFIG on failure.
(QT4_DO_MANUAL_CONFIG): remove some code.
(QT4_DO_IT_ALL): move code to handle --with-foo here; move
code to search for moc/uic here; call QT4_DO_PKG_CONFIG first,
and QT4_DO_MANUAL_CONFIG on failure.
