Hi,

Linux 6.19 will drop support for 31-bit compatibility on s390x, and will 
also stop providing 31-bit support in UAPI header files [1]. Once this 
lands in unstable, it will become impossible to build the libc6-s390 and 
libc6-dev-s390 packages on s390x. We should therefore stop building 
these packages, as well as g++-15-multilib and the corresponding lib32* 
libraries.

Doing so will break many packages. I therefore suggest that, over the 
next few weeks, we start removing 31-bit support in all packages except 
src:gcc-15, src:gcc-defaults, src:glibc, src:linux and src:zlib (and 
possibly the corresponding cross compilers?). Then in a final 
coordinated step, we can fully drop 31-bit support from those remaining 
packages as well.

Any thoughts about that? Volunteers to coordinate this? 

Regards
Aurelien
