Bug#1069169: gap-polymaking: please make the build reproducible

Source: gap-polymaking
Version: 0.8.7-2
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
gap-polymaking could not be built reproducibly.

This is because the .tst files *AND* its surrounding directory will
retain its group-writeable bit due to the use of dh_fixperms -Xtst,
and will thus vary when the package is built with a different umask.

A patch is attached that limits the "-Xtst" → "-X.tst" (to prevent the
surrounding "/tst/" directory being matched), and then normalises the
group-writable bits of the .tst files themselves.
