Bug#870573: grap: please make the build reproducible

[Chris Lamb <lamby@debian.org>]

Source: grap
Version: 1.45-1
Severity: wishlist
Tags: patch
User: reproducible-builds@lists.alioth.debian.org

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that grap could not be built reproducibly as it includes the output
of `uname -sr` in the binary.

This results in a different checksum when built on, say i386 with
running a 686 kernel and running an an amd64 kernel (again, on
i386).

Patch attached.
