For some reason Python 3 seems to think it does not need to build the library. Using the --force parameter makes sure that the library gets built always. This is especially important since we move the library in the next step of the Makefile, hence forcing a rebuild every time the higher level Makefile triggers a rebuild is required to make sure the library is always there.

It looks to me we have a genaral problem about which python is called. In fact, I am getting another issue when I build 2017.03 in Yocto. The headers like "Python.h" are taken from the distro, and not from the Yocto's buildsystem (nativepython), that makes them available.
It can be easy tested removing the package "libpython" from the host. A "bitbake u-boot", when u-boot 2017.03 is available, fails because no headers are found - but they are all available in Yocto's toolchain.
We set the "PYTHON" variable in the makefile, but this is not used consistent, as far as I see, because in some files as setup.py, "/usr/bin/env python" points to the python installed on distro - adding "PYTHON=nativepython" in u-boot recipe does not work.
