Bug#1023589: libnvme: please make the build reproducible

[Chris Lamb]

Source: libnvme
Version: 1.2-1
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
libnvme could not be built reproducibly.

This is because it embedded the current build month within the
generated manual pages. A patch is attached that re-exports
SOURCE_DATE_EPOCH as KBUILD_BUILD_TIMESTAMP. This works because the
doc/kernel-doc script already supports parsing this variable.
