Support building on AIX

[bhuntsman]

Attempting to build a ninja wheel on AIX using ninja-python-distributions fails:

(PyDevenv) $ pip -install . -vvv --no-build-isolation

Usage:   
  pip <command> [options]

no such option: -i
(PyDevenv) $ pip install . -vvv --no-build-isolation

  See above for output.
  
  note: This error originates from a subprocess, and is likely not a problem with pip.

Some details:

• Patches have been merged to scikit-build to enable this.
• This is AIX 7.3 (7300-01-01).
• The compiler in use is XL C 16.1, but I also have 17.1 as an option.
• CMake is version 3.26.4
• The header ext/hash_map is available in /opt/IBM/xlC/16.1.0/include2/c++/ext/hash_map

I could use a little help in determining, is this a problem with ninja-python-distributions, ninja itself, or CMake?

Does this still happen? Latest scikit-build's should support this.
