The timestamp of generated documentation changes from build to build.
This makes the builds not reproducible, because the timestamp changes.
RDoc has allows to override the timestamps via SOURCE_DATE_EPOCH
environment variable, which was intdouced by following PRs:

https://github.com/ruby/rdoc/pull/569/
https://github.com/ruby/rdoc/pull/570

This is related to rhbz#1719647. Nevertheless, that specific issue is
for plaid ruby- packages, so these macros cannot help with that specific
case.

In ruby-sig ML discussion [1], there was pointed out that RPM already supports this env variable, but it is not enable yet. So lets wait a bit and see if the defaults are going to be changed.
