that's certainly the cleanest solution. Though largely mechanical, I'm
not sure we want to do this before the GCC 16 release, though.

That would most certainly be welcome.
Besides, there's quite a number of effective-target keywords not even
documented in sourcebuild.texi. I mean to add those that have
documentation in target-support.exp, create a PR for the rest to prompt
the authors to fix it, and add a test like gcc.src/maintainers.exp to
ensure things remain that way. No idea when I'll get to that, though.
