Bug#1092464: kbibtex ftbfs with icu-76.1

[Matthias Klose]

Package: src:kbibtex
Version: 0.10.0-2
Severity: important
User: debian-devel at lists.debian.org
Usertags: icu76

The package fails to build with icu 76.1-2 from experimental.  The most 
likely reason is that it's not built for the default C++17 standards, 
and manually specifies an earlier standard.

The build log shows the package building with -std=gnu++11, and failing.
