py-pyobjc6: some changes to Python build system led to py*-pyobjc6 only installing docs

[barracuda156]

py-pyobjc6 was a mere restore of an earlier existing port (py-pyobjc of version 6.2.2). So it should be installing libraries etc. However, what it does now is only install documentation.

Oh wait, there is an error during the build, which is why perhaps nothing useful gets installed:

Wonder why that does not stop the build on error though and it "succeeds".

[barracuda156]

UPD. Okay, Python 3.6 was failing on a genuine error, later ones were failing on a wrong args passed to build system (which apparently became wrong due to some pep-related modifications to the PG).

[barracuda156]

Looks like there are at least three issues:

1. A move to pep517 has broken the build, so that only docs are installed (fixed now locally).
2. This does not work at all: plistlib.readPlist:

  File "/opt/local/var/macports/build/_opt_PPCSnowLeopardPorts_python_py-pyobjc6/py310-pyobjc6/work/pyobjc-core-5.3/setup.py", line 49, in get_os_level
    pl = plistlib.readPlist('/System/Library/CoreServices/SystemVersion.plist')
AttributeError: module 'plistlib' has no attribute 'readPlist'

There are multiple reports of this issue: ​https://bugzilla.redhat.com/show_bug.cgi?id=1793034 ​https://github.com/kim-do-hyeon/iphone-forensics/issues/3

3. There are minor ppc-specific errors (trivial, just fix macros).
