Issue:
======
`_lzma` is not built because the required libraries are not available on my machine. `test_zoneinfo` assumes it is always available, leading it to crash on my machine.

How I build and ran the tests:
==============================
git clone https://github.com/python/cpython.git  (bpo-41364)
cd cpython
mkdir build && cd build
../configure
make -j8
make test > test_output.txt

Test traceback:
