Recent toolchain changes rebuild

Packages that uses hardening-wrapper will need a rebuild without
it since it is being dropped from official repositories due to
recent toolchain changes (PIE and SSP enabled by default in
gcc). Although hardening-wrapper was not being used in this
package it seems a good practice to rebuild against the recent
toolchain changes.
