New issue 3127: [py37] undefined symbol: PyTraceMalloc_Untrack
https://bitbucket.org/pypy/pypy/issues/3127/py37-undefined-symbol

Jan Vesely:

Python 3.7 added new `PyTraceMalloc_Track` and `PyTraceMalloc_Untrack` functions \[0\] and for example numpy uses them.

This leads to the following error:

```
n <module>
        from numpy.core._multiarray_umath import (
    ImportError: /home/user/pypy37-venv/site-packages/numpy/core/_multiarray_umath.pypy37-pp73-x86_64-linux-gnu.so: undefined symbol: PyTraceMalloc_Untrack
```
