Generated interrogate wrapper is not deterministic on macOS

[el-dee]

Description

On macOS, the generated interrogate_wrapper.cpp is not deterministic, leading to a non-reproducible build. On Linux, the exact same build is perfectly reproductible

Steps to Reproduce

Interrogate is called with the following parameters (I removed the app include directories and files for clarity):

/Library/Developer/Panda3D/bin/interrogate -v -fnames -string -refcount -assert -python-native -S/Library/Developer/Panda3D/include/parser-inc -S/Library/Developer/Panda3D/include/ -srcdir . -oc interrogate_wrapper.cpp -od interrogate.in -module cosmonium_engine -library cosmonium_engine -nomangle -DINTERROGATE -DCPPPARSER -D__STDC__=1 -D__cplusplus=201103L files....files

SOURCE_DATE_EPOCH is set to a static value and PYTHONHASHSEED is set to 0

The diff of two generated interrogate_wrapper.cpp is as follow :

and the resulting .o files are different (A diff using objdump -d reveals different offsets)
