[Pkg-bitcoin-devel] Bug#859353: cgminer shouldn't disable PIE

[Adrian Bunk]

Source: cgminer
Version: 4.9.2-1
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.
