According to https://distrowatch.com/table.php?distribution=sle, they
also provide gcc-12.2.1 with the sp5 update, so we're probably fine.

On the other hand, I can see that OpenSUSE Leap 15.6 contains
a fairly modern kernel (6.4.x) built with the gcc-7.3 system
compiler, and I think this is the same one as in SLES.

Not sure if they plan to update the kernel release beyond that,
or how inconvenient it would be for them to require
using the other compiler for future updates, so I've added
the developers that last touched the OpenSUSE kernel RPM
package to Cc here.
