Bug#961639: util-linux: FTBFS with uname26 error on glibc >= 2.30

[Chris Hofstaedtler]

Hi Helge Deller,

thanks for your report.

Please resubmit the patch with upstreams requirements (esp.
Signed-off-by) so this can be fixed upstream. (As this does not
appear to be a Debian-specific bug.)

Thanks,
Chris
