 should look for some waf doc or so. E.g. linking steps of appcpustart.o
 into appstart.o is what makes me trouble. Also I'm not able to find out
 how rtemsbsp lib is linked and its dependency specified...

 was the first spot which needed to include a specially build object file
 in a library.

 Build builds both no-SMP and SMP BSPs fine, but neither of them runs on
 neither qemu nor on real hardware. If you find helpful, then qemu
 connected gdb shows those 3 traces over few seconds of BSP run:
