bjh21 ddf906b00d Use ld -N (OMAGIC), since this saves the 32k of RAM (by not putting a gap
between text and data) and means that loadfile only needs one backward seek
to load the file rather than two (which is important for gzipped kernels).

# This makefile is constructed from a machine description:
# config machineid
# Most changes should be made in the machine description
# /sys/arch/arm26/conf/``machineid''
# after which you should do
# config machineid
# Machine generic makefile changes should be made in
# /sys/arch/arm26/conf/Makefile.arm26
# after which config should be rerun for all machines of that type.
# DEBUG is set to -g if debugging.
# PROF is set to -pg if profiling.
