Build rootfs

Hi I'm trying to build rootfs and I'm following the exact steps on But when i
use the command 'make TARGET_PRODUCT=beagleboard
TARGET_BUILD_VARIANT=tests -j8 OMAPES=5.x' I get the following error:

I do not know if this will help: try to use gcc 4.4.
I got lots of problem when building Android-4 (ICS) in my newly installed Ubuntu-11-10 in VirtualBox which has gcc 4.6 installed. After I down graded gcc to 4.4, the problems went away.
