Subject: Switch all ec tests to using dynamic linking
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=4bec30b6d97c43070ce6facec227cd8cb2a5a470;p=openbsd

Switch all ec tests to using dynamic linking

This only requires very minor changes and simplifies testing quite a bit.
Some of the changes can be undone after the next bump.
