- removed obsolete ac25x,noobjc,am17 patches
- added dlopen-acfix patch (AC_ARG_ENABLE(dlopen ) and AC_PROG_LIBTOOL conflict)
- switched to new-style bconds, added _with_directfb
- don't disable arts on alpha (qt builds OK using gcc 3.x)
- libesd and libartsc are dlopened now, so *-devel are no longer R: by -devel
