gcc-6: Add fix for missing no-PIE flags
From: Stephen Arnold <[email protected]>
Fixes build on hardened PAX host with gcc-5 (linker error on relocs). Completes no-PIE config by adding to ALL_* flags variables. Borrowed from Gentoo gcc patches, tested on 2 hardened amd64 hosts.
Upstream-Status: Inappropriate [configuration]
