This is to turn on the code contributed by Google for optimized 64bit implementations of elliptic curves.
From the OpenSSL changelog,
Specify "enable-ec_nistp_64_gcc_128" on the Configure (or config) command
line to include this in your build of OpenSSL, and run "make depend" (or
"make update"). This enables the following EC_METHODs:
So it really is as simple as enabling an additional compile flag.
