Regenerate some autotools generated files

As discussed in
https://gcc.gnu.org/pipermail/gcc-patches/2023-June/621976.html this
should put the autotools generated files in sync to what they were
generated from (and make an automated checker happy).

Tested by bootstrapping on top of only a few revisions ago.
