efl: terrible kludge so avoid termination crash on osx

Currently, elementary programs crash on termination on macOS (seems
Sierra-specific). This is very nasty, looks like deep memory corruption...
Without valgrind (or like) support on Sierra, it is difficult to
pinpoint the origin of the problem.

Due to the imminient release, and after discussion with @stefan, this
kludge will allow the release to happen.

This commit MUST be reverted just after the release, so we don't
blindfold ourselves!
