Anyone care to comment on that:

$ make ARCH=ppc linux26-menuconfig
[ -f 
/home/guinevere/buildroot/project_build_ppc/genepy/linux-2.6.24/.config ] |
| cp local/genepy/linux-2.6.24.config 
/home/guinevere/buildroot/project_build_pp
c/genepy/linux-2.6.24/.config
/usr/bin/make -j1 HOSTCC="/usr/bin/gcc" HOSTCFLAGS="" ARCH=powerpc
[...]

Why does ARCH change ?!?

[...]
.config:132:warning: trying to assign nonexistent symbol XILINX_ML405
[...]

$ find -name Kconfig -exec grep -H XILINX_ML405 {} \;
./toolchain_build_powerpc/linux-2.6.24/arch/ppc/platforms/4xx/Kconfig:config 
XILINX_ML405
./project_build_ppc/genepy/linux-2.6.24/arch/ppc/platforms/4xx/Kconfig:config 
XILINX_ML405
./toolchain_build_ppc/linux-2.6.24/arch/ppc/platforms/4xx/Kconfig:config 
XILINX_ML405

Well, it's no surprise that it won't find them if it looks in the powerpc 
branch...
The question is why ?
