I do not understand what happened, but the luatex stuff now compiles
fine without. My best guess is that it was a snag caused by my
distribution libtool, which was not removed when I installed the
recommended versions of the autotools. But that is pure guesswork.

I also need to look at Naveen's patch for dvisvgm.
