gnulib ppc64le patch

Description of problem:
tests failed during build (make check) of m4 in ppc64le arch

Version-Release number of selected component (if applicable):
m4-1.4.17-3.fc21.ppc64le

How reproducible:
rpmbuild --target ppc64le

Actual results:
../build-aux/test-driver: line 107: 24571 Aborted                 "$@" > $log_file 2>&1
FAIL: test-isnanl-nolibm

Additional info:
floating-point test cases do not work correctly with the PowerPC long double ("double double")format.  These tests "accidentally" succeeded anyway in the big-endian variant, but are now actually failing in little-endian mode.

A patch to fix the tests for ppc64le has been submitted to upstream
to the bug-gnulib mailing list.
