[Message part 2 (message/rfc822, inline)]
This was due to a bug in uClibc. The nice folks over at Gnulib have
already pushed a workaround, which should be added to Emacs the next
time Gnulib is merged:
https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=4e082bffbcc46e68644ae0d59b4f09bf2b5feb84
I'm therefore closing this bug report. I would also recommend akater to
report this bug to the uClibc developers.
Best regards,
Stefan Kangas

I don't quite understand what I'm doing but including <stddef.h>
unconditionally in lib/getrandom.c made Emacs build without any
(relevant) warnings.
