| 2 | |
| 3 | The python build will invoke python with a custom PYTHONPATH (pointing to |
| 4 | local libs) which will mess up any python scripts we execute, like our |
| 5 | compiler wrapper. |
| 6 | |
| 7 | We can't create wrappers and point the build at those because python will |
| 8 | record the values for CC/CXX and write it out to its installed modules, and |
| 9 | those values will be loaded later when cross-compiling other python packages. |
| 10 | |
| 11 | This hack is kind of terrible, but so are many of the alternatives. |
