Dear Maintainer,
While working on the “reproducible builds” effort [1], we have noticed
that 'crawl' could not be built reproducibly.
The attached patch fixes the order in which maps are listed, and strips
build date from the version string.
Once applied, crawl can be built reproducibly in our current
experimental framework.
Regards,
Alexis Bienvenüe.
