Add _LARGE_FILES to def_macros[] when platform is AIX (gh-15938)
BUG: Add _LARGE_FILES to def_macros[] when platform is AIX (gh-15938)

AIX needs to be told to use large file support at all times. Fixes parts of gh-15801.

Add _LARGE_FILES to def_macros[] when platform is AIX (gh-15938)
## Code Before:

def configuration(parent_package='',top_path=None):
    from numpy.distutils.misc_util import Configuration
    config = Configuration('fft', parent_package, top_path)

    config.add_data_dir('tests')

                         sources=['_pocketfft.c']
                         )

    return config

if __name__ == '__main__':
    from numpy.distutils.core import setup
