[Debian-med-packaging] Bug#865655: pirs shouldn't disable PIE

[Adrian Bunk]

Source: pirs
Version: 2.0.2+dfsg-5.1
Severity: normal
Tags: patch

With gcc in stretch defaulting to PIE, hardening=+all,-pie changed
semantics from "enable hardening but not PIE" to "enable all hardening
and explicitely disable the default PIE".
The latter is usually not intended.

The -pie in hardening flags was in some cases required in pre-stretch
releases to avoid build failures caused by (incorrectly) passing -fPIE
to the compiler when building shared libraries or plugins.
This problem does no longer exist.

Please consider applying the following patch:
