Python3.8.0のコンパイルにOpenSSL 1.0.2 以上が必要らしい。
でも、Debian openssl で検索すると、
パッケージ: openssl (1.0.1t-1+deb8u12) [security]
なので、openSSLのダウンロードページからダウンロードしてビルド。
参考：LinuxにApacheとOpenSSLをソースからビルドしてインストールする
$ wget https://www.openssl.org/source/openssl-1.0.2t.tar.gz
$ tar xvzf openssl-1.0.2t.tar.gz
・・・
$ cd openssl-1.0.2t
$ sudo ./config --prefix=/usr/local/openssl-1.0.2t shared zlib
・・・
Configured for linux-armv4.
$ sudo make
・・・
$ sudo make install
penSSL shared libraries have been installed in:
/usr/local/openssl-1.0.2t
If this directory is not in a standard system path for dynamic/shared
libraries, then you will have problems linking and executing
applications that use OpenSSL libraries UNLESS:
* you link with static (archive) libraries. If you are truly
paranoid about security, you should use static libraries.
* you use the GNU libtool code during linking
(http://www.gnu.org/software/libtool/libtool.html)
* you use pkg-config during linking (this requires that
PKG_CONFIG_PATH includes the path to the OpenSSL shared
library directory), and make use of -R or -rpath.
(http://www.freedesktop.org/software/pkgconfig/)
* you specify the system-wide link path via a command such
as crle(1) on Solaris systems.
* you add the OpenSSL shared library directory to /etc/ld.so.conf
and run ldconfig(8) on Linux systems.
* you define the LD_LIBRARY_PATH, LIBPATH, SHLIB_PATH (HP),
DYLD_LIBRARY_PATH (MacOS X) or PATH (Cygwin and DJGPP)
environment variable and add the OpenSSL shared library
directory to it.
One common tool to check the dynamic dependencies of an executable
or dynamic library is ldd(1) on most UNIX systems.
See any operating system documentation and manpages about shared
libraries for your version of UNIX. The following manpages may be
helpful: ld(1), ld.so(1), ld.so.1(1) [Solaris], dld.sl(1) [HP],
ldd(1), crle(1) [Solaris], pldd(1) [Solaris], ldconfig(8) [Linux],
chatr(1) [HP].

あれれ？名前が1.0.0じゃないか？？？
Pythonは1.0.2以上がががとエラる。
諦めて最新の安定版ver1.1.1dを試す。
