One-liner patch to fix this particular build issue

Description of problem:

findutils 4.5.10-5.fc18 (current version in rawhide) will not build when automake 1.12.2-5.fc18 (current version in rawhide) is used to generate 'configure'.

Version-Release number of selected component (if applicable):

4.5.10-5.fc18

How reproducible:

Always

Steps to Reproduce:
1. Install (or build/install) automake 1.12.2-5.fc18 on build host.
2. Run 'rpmbuild --rebuild findutils-4.5.10-5.fc18.src.rpm' on build host.
  
Actual results:

The build fails during %setup during 'aclocal -I gnu lib/m4 -I m4'.

Build should progress beyond this point.

Additional info:

http://lists.gnu.org/archive/html/bug-findutils/2011-10/msg00002.html explains the background behind this problem.

I have attached a one-liner patch to fix as suggested and the build then progresses beyond this point; unfortunately, it then breaks due to what I suspect is an outdated copy of gnulib bundled in findutils which is incompatible with glibc 2.16 :-(
