Testing the Debian release cross compilers/binutils:

Debian 10 / gcc 8.3.0  / ld 2.31.1: generates the warning

Debian 11 / gcc 10.2.1 / ld 2.35.2: generates the warning

Debian 12 / gcc 12.2.0 / ld 2.40:   does _not_ generate the warning

I suppose moving to the newer toolchain is the workaround. Although it
is a bit unusual to require such a modern toolchain in order to build a
kernel without warnings.
