I got eventually a shell on a power5 box to test some stuff.
I’m trying discover what’s broken in glibc and/or gcc when you try to build as ppc64, currently busybox has some problems with setjmp symbols if you try to build it static, while trying snapshots I ended up in having other issues with gcc-4.2 snapshot not building glibc-2.5 and that looks like yet another pain =/
Luckly the box is fast enough to not take that much building and rebuilding glibc =)
