| distutils: fix build_ext check to find whether we're building Python or not |
| |
| The build_ext logic uses |
| sys.executable.startswith(os.path.join(sys.exec_prefix, "bin")) to |
| determine whether we're building a third-party Python extension, or a |
| built-in Python extension. However, this check is wrong in |
| cross-compilation mode, and instead, the sysconfig.python_build |
| variable should be used. |
