Hem, I'm not good at that. In fact I use my distribution rpm spec file to rebuild mesa.

In this file, I find (last-line is the important one):

%make   MKDEP=/usr/bin/makedepend \
        USING_EGL=%{enable_egl} \
        DRI_DIRS=%{dri_drivers} \
        DRI_DRIVER_SEARCH_DIR=%{driver_dir} \
        LIB_DIR=$LIB_DIR \
        linux-dri

So can I suppose it is already built with 'linux-dri'?
