Thanks, removing that file allowed configure to complete, but now I get
this:

checking that generated files are newer than configure... done
configure: creating ./config.status
make: *** No rule to make target 'lib/gnulib.mk.in', needed by 'Makefile'.  
Stop.

git bisect skip doesn't eliminate this failure.

My guess is the first of these, since it's between the bad and good
builds; the other two commits are much earlier.  But given the above
make failure, I don't know how to build that commit (or the one before
