[meta-xilinx] [meta-xilinx-tools] error while building pmu-firmware

[Ahsan, Noor]

Hello,

I was trying to build pmu-firmware and faced following error

ERROR: pmu-firmware-2018.2+gitAUTOINC+6e82c0183b-r0 do_create_yaml: Error executing a python function in exec_python_func() autogenerated:

The stack trace of python calls that resulted in this exception/failure was:
File: 'exec_python_func() autogenerated', lineno: 2, function: <module>
     0001:

     0003:

     0063:    os.sys.path.append(os.path.join(d.getVar('RECIPE_SYSROOT_NATIVE'),d.getVar('PYTHON_SITEPACKAGES_DIR')[1::]))

     0068:    if appconfig:
Exception: ImportError: No module named 'yaml'

ERROR: pmu-firmware-2018.2+gitAUTOINC+6e82c0183b-r0 do_create_yaml: Function failed: do_create_yaml

Although we this line in class just before importing yaml

os.sys.path.append(os.path.join(d.getVar('RECIPE_SYSROOT_NATIVE'),d.getVar('PYTHON_SITEPACKAGES_DIR')[1::]))
https://github.com/Xilinx/meta-xilinx-tools/blob/rel-v2018.2/classes/xsctyaml.bbclass#L63

but I think this is not correct as for 64bit architecture the PYTHON_SITEPACKAGES_DIR is set to /usr/lib64/python3.5/site-packages but python native will be location in /usr/lib/.... not in /usr/lib64. This will cause the above error that I am getting. Have anybody seen this issue?
