Comment:
Adding boost-python3-1.69 to {host,}makedepends is not necessary, boost-devel is enough, the shlib itself is auto-detected by xbps.

`--with-boost-python=boost_python36` needs to be set explicitly, otherwise it picks up python27:
```
Boost libraries:
  boost.python:         -lboost_python27
```
