[uClibc] is gcc correct for armeb - xscale cpp ?

Wed Jan 5 13:25:19 UTC 2005

I have build armeb - big Endian - xscale using
buildroot but I noticed the my compiler is NOT for
xscale with cpp support.

from the dumpspecs of gcc

*cpp_cpu_arch_default:
-D__ARM_ARCH_3__

Is there some other option I need to give to menu
config or is cpp just getting it wrong.

regards,

Philip
