yet another alternative libc

["Anthony G. Basile" <blueness-aBrp7R+bbdUdnm+yROfE0A@public.gmane.org>]

Hi everyone,

I just thought I'd let everyone know that I've built a musl stage4 for 
amd64 and put it on the mirrors [1].  If you don't know about musl, you 
can read about it here [2].  Its yet another libc which aims to be a 
slim and fast.

I've got a stage4 (kinda/sorta).  It is not made using catalyst but 
rather starts from a musl chroot and builds a new chroot using a 
ROOT=rootfs emerge -ev @system technique.  The scripts are on the releng 
repo [3].  Right now there are lots of packages which do not immediately 
build with musl.  Mostly these are due to header locations, gnu-isms, 
gnulib (which assumes way too much about internal implementations) and 
at least one bug in musl or gcc (depending on who you ask --- exit() 
compiled with --stack-protector-all).  The patches are on the 
hardened-dev::musl overlay [4].  They are "quickies" and may need work 
if any are to go upstream.

A few points about the stage: 1) it doesn't use busybox for its core 
utilities.  I like a robust native development environment from which 
you can build.  2) Despite the fact that the profile is under hardened, 
it is still a vanilla stage.  I'm working on getting it hardened, but a 
few packages break when we turn on pie, ssp, relro and/or bind_now.

Enjoy or ignore at your discretion.
