    Allow osmesa to be enabled or disabled
    
    The conditional in src/mesa/Makefile currently hardcodes the cases where
    libOSMesa can be built on libGL. Likewise, the xlib case always includes
    libOSMesa in the stand-alone target.
    
    This changes the conditional to a loop over the DRIVER_DIRS variable.
    This means that any driver configuration can enable or disable osmesa.
    The current "stand-alone" rule is changed so that DRIVER_DIRS=x11 and
    DRIVER_DIRS="x11 osmesa" are both respected.
    
    The configure option is changed to --enable-gl-osmesa as this change
    allows libOSMesa to be built upon any of the libGL-enabling drivers.
