* This patchset add a switch to configure gcc driver with PIE defaults
* Add support for generating static PIE in gcc
* Gets rid of lot of bandaids from distro security flags file
* Adjust recipes for new way of specifying pie

v1->v2:

* apply linking spec changes libssp_nonshared.a to musl alone
* icu/iptable/gstreamer1.0-plugins-bad fixes are done on top not really depend on pie rework
