[oe] [meta-python][PATCH] python3-importlib-metadata: fix class-target overriding default dependencies

[nick83ola]

Hi Ross,

thanks for your response.

So do you suggest to modify in python3_3.7.5.bb:

    # First set RPROVIDES for -native case
    # Hardcoded since it cant be python3-native-foo, should be
python3-foo-native
    pn = 'python3'
    rprovides = d.getVar('RPROVIDES').split()
    rprovides.append(pn + '-misc-native')

    for key in python_manifest:
        pypackage = pn + '-' + key + '-native'
        if pypackage not in rprovides:
              rprovides.append(pypackage)

        d.setVar('RPROVIDES_class-native', ' '.join(rprovides))


(Or to add an RPROVIDES ayt the end -> is more explicit mabe? this function
is getting rprovides = d.getVar('RPROVIDES').split() )

This change I imagine needs to be done also for python2?

Cheers
Nicola Lunghi
