Not for me. Applying this patch, my generated Makefile.in ends up
containing:

ELCFILES = \\
         $(lisp)/abbrev.elc \

rather than

ELCFILES = \
         $(lisp)/abbrev.elc \

I guess it's something to do with sed and/or /bin/sh versions.

(It's not vital that this command work for everyone, though of course
that is what I would like.)
