Several files in Documentation have an unstable 'Last updated' timestamp. The
reason is that their mtime changes every time, which prevents reproducible
builds.

342 technical/api-index.sh $(patsubst %,%.txt,$(API_DOCS))
343 $(QUIET_GEN)cd technical && '$(SHELL_PATH_SQ)' ./api-index.sh
388 howto-index.txt: howto-index.sh $(wildcard howto/*.txt)
389 $(QUIET_GEN)$(RM) $@+ $@ && \
390 '$(SHELL_PATH_SQ)' ./howto-index.sh $(sort $(wildcard howto/*.txt)) >$@+ && \
391 mv $@+ $@
399 $(patsubst %.txt,%.html,$(wildcard howto/*.txt)): %.html : %.txt
400 $(QUIET_ASCIIDOC)$(RM) $@+ $@ && \
401 sed -e '1,/^$$/d' $< | \
402 $(TXT_TO_HTML) - >$@+ && \
403 mv $@+ $@
What file timestamp should be used for them? Likely "../version"?
The final file, before passing it to asciidoc, should get a fixed timestamp
with 'touch -r $reference_file $file'.
