RV9Flyer, the arm-none-eabi-gcc cross-compiler is in my humble understanding intended for use with' bare-metal' 'non-mmu' 'sans Linux' ARM microcontrollers..specifically the Cortex-R/Cortex-M cores.
You need to use a different toolchain for Linux-based, MMU-based Cortex-A setups such as that of the beaglebone black. typically the cross-compiler toolchain that you should use should be called arm-linux-gnueabiXX-gcc. I'm not sure where you can get such a toolchain for angstrom....you could probably build it with openembedded/yocto.
