Re: Make documentation builds reproducible

Hi,

I usually the HTML documentation locally using command:

make STYLE=website html

~

This has been working forever, but seems to have broken due to commit
[1] having an undeclared variable.

e.g.
[postgres@CentOS7-x64 sgml]$ make STYLE=website html
{ \
  echo "<!ENTITY version \"17devel\">"; \
  echo "<!ENTITY majorversion \"17\">"; \
} > version.sgml
