[uClibc] toolchain: ppc assembler error ( .section ".relocate_code", "xa") when compiling linux 2.6.1 kernel???

[Ken McGuire]

I guess I'll reply to my post as an update.
 I  regressed binutils to 2.14.90.0.7 from the 2.95 toolchain part of cvs. I was able to use this 
and buildroot to build a working uClibc-2.95 toolcahin & root fs including busybox. I then was able 
to use the toolchain to build a 2.4.25 kernel for my Motorola MCP750/HA CPCI board. It booted fine 
over the network and I was then able to copy the rootfs to a hdd and the kernel to a PREP 
partition. The combo booted off the hdd. I was then able to create a initrd from the rootfs I built 
using buildroot & busybox 1.0rc3, that combo booted via the network. So I now have a working PPC 
system.
 The net is littered with partly complete PREP architecture PPC kernels and non working 
distributions. After searching high & low I finally decided to start from the sources and build my 
own.Thanks to buildroot, uclibc & busybox this (not without some pain & effort) this was possible 
for a hardware engineer like me to do.

 Thanks to all the uClibc/busybox/buildroot developers for a fine set of tools & discussions which 
answeed most of my stupid questions without me having to really ask them. ;>)
