fwiw, fwknop actually only uses this value by passing it to
gpgme_set_engine_info() if the user hasn't explicitly asked for a
non-default value:

 https://sources.debian.net/src/fwknop/2.6.0-4/lib/gpgme_funcs.c/?hl=67#L63

But gpgme clearly automatically selects the preferred value if it is
passed NULL here:

 https://sources.debian.net/src/gpgme1.0/1.6.0-3/src/engine.c/?hl=368#L351

So the right upstream fix would be to strip out any hardcoded defaults
in fwknop, remove the configure.ac variable, and pass NULL to
gpgme_set_version_info() unless the user explicitly specifies otherwise.

hth,
