no-OS support for Vivado-2019.2

I noticed that the no-OS master branch still expects the HDL output in the *.hdf format.

The HDL master and the vivado_2019_2_upgrade branch supports the new *.xsa format.

When I try to build a no-OS project, it fails, since it expects to find a corresponding *.hdf file.

make M_HDF_FILE=/<path_to_hdf>/system_top.hdf

Would it be possible to have the no-OS master branch update to support the *.xsa format?
