It is not new with gcc 11.3 and binutils 2.38. I currently use gcc 11.2.0
combined with binutils 2.36.1 for building powerpc images (binutils 2.37
won't work, at least not with gcc 11.2).

With this patch applied, at least the affected file builds with gcc 11.3 /
binutils 2.38. I have not tried to build the entire image, though, with that
combination.
