But honestly, is it worth the trouble?  If we do that we have to
content with at least these issues:

  - $build != $host; can not run GDB at all
  - Expat not available; can not parse descriptions
  - GDB needs the descriptions to build but can't regenerate them
    until after it is built.

I don't think it's important enough to make the build system
more complicated.
