Hello all, this is a series of patches against the toolchian-funcs and toolchain-glibc eclasses, most notably
- introducing new tc-enables-pie(), tc-enables-ssp(), tc-enables-ssp-strong() and tc-enables-ssp-all() functions in toolchain-funcs compatible with gcc >=6 and clang as a replacement for the old gcc-specs-* functions (patch 1). After this patchset is merged, I will follow up with fixes to a (small) number of ebuilds and eclasses utilizing the old gcc-specs-* functions so that we can deprecate those relatively quickly. - updates toolchain-glibc to use said new variants and removing obsolete configuration logic for gcc >=6. [1] - enables a number of (upstreamed) security features for glibc-2.25 per default.
