Hi everyone,

I just wanted to let everyone know that I've put some experimental 
uclibc stage4's on the mirror.  They're in 
experimental/{amd64,i686,mips}/uclibc and here's what they are:

1. I call them stage4 because they have more than stage3 in them and 
they are not built with catalyst nor by cross compiling.  The mips were 
initially seeded via cross compiling with buildroot, but then I used 
that environment to bootstrap into a full system on native hardware via 
something like ROOT=rootfs emerge -e world. ie.  I did what catalyst 
does manually.

2. They are uclibc so they are aimed at embedded systems.  The mips are 
aimed at boards like the mikrotik rb450g's, ubiquity's routerstations or 
other similar.

3. The mips are mips = big endian and mipsel = little endian.  They are 
MIPS III (in uclibc's config CONFIG_MIPS_ISA_3=y) for maximum compat.

4. The mips are abi = o32.  The amd64 and i686 are their classical 
abi's.  No x32.

5. They have full hardening = PIE and SSP like glibc that the hardened 
team takes care of.  I've also include the vanilla stage4 counterparts 
for completeness.

6. They are not fully in tree yet.  The mips make use of the profiles 
and gcc-4.6.3-r99 from the hardened-dev::uclibc overlay.  The 
{amd64,i686} make use of the profiles from the same overlay.  I'm in the 
process of moving everything to the tree.  The next iteration of 
{amd64,i686} will be 100% in tree.

7. They are not hack-ish in that if you do an emerge -q world the entire 
chroot will rebuild cleanly.

This is work that Zorry and I have been at for years.  The pieces are 
finally starting to come together for something polished enough for the 
community.  Hopefully I'll have arm and ppc by the end of summer.
