- mesa-7.1-link-shared.patch: Make a libdricore.so from libmesa.a, install

it into %_libdir/dri, and link the DRI drivers against it. Drops ~20M
    from the installed system (not including debuginfo). Inspired by a
    similar patch in openSUSE but reworked to be compatible with the OSMesa
    build.
