Subject: [PATCH] Updated QT rules

All temporary files are automatically put under _build and binaries under
_compiled. Also LDFLAGS are propagated to qmake-generated Makefile. Clean
target works correctly and no special target for distclean is needed as
everything is put under _build.

This behavior is problematic during development of QT application since it
cannot be compiled by running make in sources directory.
