PIE static libraries rebuild / Recent toolchain changes rebuild

The recent toolchain changes (PIE and SSP enabled by default in
gcc) makes the need to rebuild packages that uses static
libraries as makedepends. A static library that is in makedepends
of ffmpeg-full have triggered a rebuild (libmfx).

Also, packages that uses hardening-wrapper will need a rebuild
without it since it is being dropped from official repositories
due to the recent toolchain changes. Although hardening-wrapper
was not being used in this package it is a good practice to
rebuild against the recent toolchain changes.
