make ARCH=arm CROSS_COMPILE=armv5compiler

NOTE: replace the armv5compiler with your ARM v5 cross compiler.

This produces the following images:

• barebox-karo-tx28-bootstream.img - Use with the bcb command
• barebox-karo-tx28-sd.img - Use for SD cards
• barebox-karo-tx28-2nd.img - Use for 2nd stage booting (with bootm)
