description:
fix building x86 with X11 but not LLVM:

- change the defaults for MKLLVMRT and MKX11 so we don't have to
  force-override later.  this makes "build.sh -V MKLLVMRT=no"
  work to disable building the LLVM Mesa components.

- in gallium, don't BUILD_RADEON if MKLLVMRT is no.

this stops GL from working, but basic X seems OK enough for Xvideo
to still work on modern radeon (ie, video mostly works fine, though
eg, "mpv -vo gpu" won't.  use "mpv -vo xv".)
