The build with and without libunwind and libdw has been tested
succesfully on ARM, including the paths to the desired libraries.
Of course I am getting a link error on
'libdw__arch_set_initial_registers' because the ARM support is not yet
in.

Here is an ack on the series:
Acked-by: Jean Pihet <jean.pihet@...aro.org>

Next on my plate: implement the ARM specifics.

Thanks!
Jean
