[Pkg-ace-devel] Bug#859350: ace shouldn't disable PIE

[Adrian Bunk]

Source: ace
Version: 6.3.3+dfsg-1.2
Severity: normal
Tags: patch

With gcc in stretch defaulting to PIE, hardening=...,-pie changed
semantics from "enable hardening but not PIE" to "enable 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 change:
