When cross-compiling third-party extensions, get_python_inc() may be called to return the path to Python's headers. However, it uses the sys.prefix or sys.exec_prefix of the build Python, which returns incorrect paths when cross-compiling (paths pointing to build system headers). To fix this, we use the INCLUDEPY and CONFINCLUDEPY conf variables, which can be configured to point at host Python by setting _PYTHON_SYSCONFIGDATA_NAME. The existing behavior is maintained on non-POSIX platforms or if a prefix is manually specified.
