[Python] Unable to build pyarrow wheels with manylinux2014 for ppc64le arch

Hi, I'm trying to build wheels for ppc64le with manylinux2014 following the [documentation](https://arrow.apache.org/docs/developers/python.html#building-on-linux-and-macos) but when I'm executing the cmake command I'm getting this issue:
```java

[...]

Anyone knows what is going wrong here? I installed numpy via the requirements files.

Start by reproducing the documented manylinux2014 ppc64le build and its CMake configure command with Python 3.7 and NumPy installed from the requirements files. Read cmake_modules/FindPython3Alt.cmake and src/arrow/python/CMakeLists.txt to trace the missing Python development components. Done means CMake configures successfully and the Python wheel build completes.
