Thanks for the help, I did what you suggested with some minor
adjustment. I am still getting errors from fontconfig and freetype,
though:

  Fontconfig error: Cannot load default config file
  warning: could not match any font: *-normal-normal-10
  warning: ft_render: unable to load appropriate font

I'm no fontconfig expert, but I think this tells me that it's not
finding the configuration file from that variable. Do I need to inherit
the FONTCONFIG_FILE variable to get it into the build environment? Or
copy the file into the octave build directory?

I'm at a loss how to debug this further for now. Thanks for any more
advice you can offer.
