Experimental RTnet ARM build

[Jan Kiszka]

Hello,

today I switched on the ARM architecture in RTnet's configure and tried 
to build with some half-baked cross-environment (I have not real ARM 
hardware around). The test was against RTAI 3.2 (CVS) and kernel 2.6.7. 
Compilation worked except for the lxrt userspace example. If it may 
already run - don't know. We are lacking at least some drivers for 
specific on-board NICs, but "useless" rt_loopback should work. If one of 
the ARM gurus around have the time, please take a look at the RTnet SVN 
and report problems back.

Thanks,
Jan
