The gnulib largefile macro needs updating to work with autoconf 2.73. Rather
than the full code:

https://git.savannah.gnu.org/cgit/gnulib.git/commit/m4/largefile.m4?id=f91f633858cf132e50924224c50d6264a92caabb

Just tweak the exiting code to work with 2.73. The next libpipeline upgrade should
update to new gnulib
