bug in glibc package

[Alex King]

In Debian 9 Stretch, I am seeing this bug 
(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=987266).

This means that when I try to use a kernel with a revision later than 
254 i get an error, e.g. I'm trying to use a 4.14.264 kernel.

It seems like this is a simple fix, (e.g. just take the offending block 
out, 
https://salsa.debian.org/glibc-team/glibc/-/commit/b3c76cf1cd0c8b6e4844c6362a45143c136a2900).

If that was acceptable, how would I go about getting this into LTS? 
Happy to do a little work on it if I knew what to do.

Thanks,
Alex King
