Re: [gentoo-embedded] uclibc don't compile with USE="hardened"

[Ned Ludd]

I've run into this when using spanky's stages. 
Oddly enough it does not happen for me when I started with the 
initial hardened stage1 from Peter, nor any time I remerge uclibc and I
use the hardened exclusively. Anyway chances of a user getting his/her
userland correct when using a non hardened-uclibc stage are probably
slim, unless your willing to recompile everything a few times. The 
default method in the future will be to start from a hardened-uclibc
stage. 

Anyway if you want a binary pkgs of a hardened uclibc toolchain I can
post them for you.  From then on you should be able to recompile your
world correctly.

Oh and let me know when you have a patch that fixes this.
