But unfortunately, adding ../../lang/libunwind/buildlink3.mk does not
solve the problem.

I ended up making, by hand, symbolic links in .buildlink/include/ and
.buildlink/lib/, with the added caveat that libunwind.h is including
__libunwind_config.h so that one has to symlink this one as well.

So thanks! because this was the bit I haven't find: where to put the
needed files under the compiling process nose.
