[s390] Build failure with gcc 4.9.2 in rawhide

[Siddhesh Poyarekar]

Hi Andreas,

We encountered a build failure in rawhide for s390x due to -Werror:

http://s390.koji.fedoraproject.org/koji/getfile?taskID=1705688&name=build.log&offset=-24000

I was able to narrow it to a small reproducer and have filed it as a
bug in gcc:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64739

I have unbroken the build temporarily in Fedora by disabling werror
for s390x.  Could you please have this patched in glibc before the
release?

Thanks,
Siddhesh
