Sorry for not getting back earlier; I have limited internet access
right now.

I _am_ watchdog co-maintainer, so I guess it is partially my fault.
Wim normally handles pull requests. I had asked him to send a pull
request with this patch, but unfortunately he didn't reply.

Not all of them, but that is nothing news and unrelated to -Werror.
Many 'minor' architectures do not and never did successfully build
allmodconfig, and others (nds32) need a specific gcc/binutils version
to build it. I submitted a set of patches for csky to enable it to build
allmodconfig with upstream gcc, so maybe we'll get that in 5.16. For
others it may be a lost cause. I can create a list with build errors
if there is interest.
