Patch from David Fiddes <D.J.Fiddes@…>. Comments below:

With a bit of help from Ralf I was able to trace the problem with sed. It
was a typo, sed should have had it's params surrounded by 's rather than "s
which bash picked up and discarded. The patch is enclosed.

Ralf and I aren't sure why configure didn't just stop at this point... The
rest of configure/build went OK because there are two sections where the

-for-/ hack is implemented and the other one is more important and worked
just fine.
