Accepting request 211829 from openSUSE:Factory:PowerLE
The "gnulib" package contains a number of floating-point test cases that 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. As is usual for gnulib, those tests end up copied into the source code of various packages that use gnulib, including coreutils, findutils, grep, and libunistring. A patch to fix the tests for ppc64le has been submitted to upstream to the bug-gnulib mailing list. We'll work with upstream of the other affected packages to make sure the copies are refreshed. - coreutils-gnulib-tests-ppc64le.patch: Fix imported gnulib long double math tests for little-endian PowerPC.
