OK, it might be easyer than I thought to get a pkg for 1.6.
Can you try something like the following:

PTHREAD_OPTS+= native
.include "../../mk/pthread.buildlink3.mk"
.if defined(PTHREAD_TYPE) && ${PTHREAD_TYPE} == "native"
PLIST_SUBST+= HAVE_THR=""
.else
PLIST_SUBST+= HAVE_THR="@comment "
.endif

and put a "${HAVE_THR}" in front of the pthread.dll PLIST entry.
