Reproducible build date

Reported by: myon Owned by: Algunenano
Priority: medium Milestone: PostGIS 2.5.0
Component: postgis Version: master
Keywords: Cc: sebastic

Description

Debian aims at providing binary packages that can be reproduced bit-identical when rebuilt. A common source of variation are embedded "built at" strings, and indeed PostGIS has this problem. To address this problem the SOURCE_DATE_EPOCH specification was created: ​https://reproducible-builds.org/specs/source-date-epoch/

The attached patch makes configure.ac honor the SOURCE_DATE_EPOCH variable when present in the build environment.

Owner: changed from pramsey to Algunenano

I'm guessing this will should be applied both to POSTGIS_BUILD_DATE and POSTGIS_RASTER_BUILD_DATE.

@myon, Can you please confirm your name / alias for the commit message and NEWS file?

@Algunenano: oh, sorry for missing POSTGIS_RASTER_BUILD_DATE. I did some grepping on the resulting files but apparently missed that timestamp.
