Version: 1.8.0+dfsg1-3
Severity: normal

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.
