    gcc-6: Add fix for missing no-PIE flags
    
    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]
