Sorry, there was also this:

<https://sourceware.org/ml/libc-alpha/2019-05/msg00629.html>

I also posted a build-many-glibcs.py patch at some point with an
automatic table update, but that still had the massive bot-cycle time.

My current line of thinking is to implement some --use-compilers flag,
so that you can build a fresh glibc checkout against an old, pre-built
compilers for the system call tables update, and then use the patched
glibc sources for one (and hopefully final) bot-cycle.

Thanks,
Florian
