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.
