Building toolchain using yocto for running linux on Xilinx ML-507

Hi,

I'm trying to build linux using yocto for the ML-507 board.

I've added the meta-xilinx layer, and modified my build/conf/local.conf file as follows:

# Set the target machine details

MACHINE ?= "virtex5"

# Set Xilinx Platform Studio hardware project path

XILINX_BSP_PATH ?= "/project/xilinx-ml507"

# Set target board

XILINX_BOARD ?= "ml507"

and when I try to build the meta-toolchain

$ cd /tool/yocto/poky

$ source oe-init-build-env build

$ bitbake meta-toolchain

I get the following errors:

ERROR: Execution of event handler 'check_sanity_eventhandler' failed

Summary: There were 3 ERROR messages shown, returning a non-zero exit code.

Has support for the PowerPC440 processor been removed from newer gcc-versions (e.g. gcc-4.4.x or gcc-4.5.x)?
