I maintain stage3 tarballs (that's minimal system with full toolchain) 
for multiple arches.  I hit elfutils because some of these stage3's are 
"hardened" meaning that they are meant to run with a pax hardened 
kernel.  These require "marking" of some elf objects which is done by a 
utility I wrote called paxutils-ng.  This depends on elfutils

Take a look at:

downloads for ...
amd64:

x86:

mipsel3 + mips32r2:

ppc: (vanilla only)

I also maintain a full desktop system using uclibc for amd64 only.  The 
purpose is to push uclibc to the limits and hit as many implementation 
level bugs.

I also maintain similar stages for musl:

I hope this stuff is useful to you.
