General observations on the patch series:
* You're missing user documentation, in invoke.texi or elsewhere, to
explain new options relating to using this new feature.
* You're regenerating configure scripts with a patched autoconf version
that adds --runstatedir options. You need to regenerate with *unpatched*
auto*.
* You're missing documentation of bootstrap-hwasan (in install.texi).
