 Right, though I guess the big question is why it doesn't fail in releng
 builds for the 11 branch. Hmm.
 
 (The GCC 14 change -- for riscv, specifically -- hadn't made it into
 the doc/CHANGES document, so I just updated it.)

 I've been regularly cross-compiling HEAD for aarch64 on amd64 for many
 months (before the GCC update to 14.3) and have never encountered this
 issue there (on more than one machine, ranging from -j 4 to -j 16).
