[Buildroot] .exit.data referenced in section .exit.text of drivers/built-in.o

[Guillaume Dargaud <dargaud@lpsc.in2p3.fr>]

Hello all, beware newbie speaking...

I've been trying to get buildroot to build me a system for a Xilinx ML405 
board for a few days. It's a great tool you have here and I was able to get 
over the first few problems I had with it pretty quickly, I now have the 
cross-compiler, busybox and other things compiled.

[
Minor bugs are that buildroot seems to require the presence of the empty dir 
/kernel-patches-2.6.24 and the link /linux-2.6.24.config -> 
/home/guinevere/buildroot/project_build_ppc/genepy/linux-2.6.24/.config
There's probably a relative path missing somewhere
]

The one thing missing is the kernel which fails in its final linking stage 
with
`.exit.data' referenced in section `.exit.text' of drivers/built-in.o: 
defined in discarded section `.exit.dilt-in.o

I tried with 2.6.24, 2.6.24.3, 2.6.23, 2.6.22.10 and get the same error...

Here's a complete output:
