Python 3.8.6(rc1) ソースをダウンロードして、configure, make

  途中で、gcc, make がないと言われたので、apt installする。

Makefileが出来上がったところでmake している。
  testも通って、いろんなmoduleをmakeしている。 (build?)

Could not build the ssl module!
Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with X509_VERIFY_PARAM_set1_host().
LibreSSL 2.6.4 and earlier do not provide the necessary APIs, https://github.com/libressl-portable/portable/issues/381
