It can now handle OpenSSL versions 1.0.2e and greater, which don't
include include files in include/.
Note that sources prepared by this script no longer support the old
project files for 2.7; you now have to have Perl available to use
the old build_ssl.py script with sources from svn.python.org.
This change affects the makefiles checked into svn.python.org, which the 3.5
build no longer uses. 3.4 and 2.7 both still use those makefiles, but their
build_ssl.py scripts don't require an update; if the script is running the
'fix_makefiles' method it already has Perl available anyway.
instead relying on OpenSSL source being configured and ready to build. The
``PCbuild\build_ssl.py`` script has been re-written and re-named to
``PCbuild\prepare_ssl.py``, and takes care of configuring OpenSSL source
for both 32 and 64 bit platforms. OpenSSL sources obtained from
svn.python.org will always be pre-configured and ready to build.
