I've made some progress on this. There was something wrong on my setup
that made it use some toolchain apps from Xilinx but some others from
buildroot,
so it's even a miracle it reached that far. Once solved lots of environment
variables
and the like, there remains just this one error on compilation:

collect2: error: ld returned 1 exit status

So... back to square oneI guess. I don't know what to do with this now.


Best regards
