Gentoo binutils >= 2.14.90.0.8-r? should have pie support, all 2.15 have it "natively". For gcc-3.3.5-r1 I have attached a patch that solves 2 problems: a. allows starting from a non-hardened stage1 to build a hardened system (libiberty-pic patch was removed for some reason) b. allows to cross-compile (tested for arm on x86) > > If either you or Mike have time, could you write what you know about > which binutils to install for which cross-compiler on the wiki?

Mike has following info about arm: glibc fails w/ other binutils than 2.14.90.0.6 (not usable for hardened) and 2.15.90.0.3, until glibc cant be built natively w/ other binutils, none other will be considered ok for arm the same applies to gcc, only gcc >= 3.3.5-r1 && < 3.4 can build glibc on arm natively I have following info: dont use hardened,pic,pie on arm (pie creation produces currently text relocations in all bins), also all libs have TEXTREL. I havent had the possibility to check further, but it seems to be a toolchain issue. If you want some sort of hardened enhancement on arm, you may use an ssp enabled specs config for gcc.
