FYI, I reverted this, because its test suite consistently fails on i686
with errors that appear to indicate a genuine problem.  Gsl is an
important package that many other packages depend on, e.g. inkscape,
which is needed to convert our grub background, and therefore we have
been unable to build i686 systems since this update.

  https://hydra.gnu.org/build/1463044
  https://hydra.gnu.org/eval/109125#tabs-now-fail

See below for details from a failed build on my i686 machine.
