Hi Ben.
After configure, if i run make in the top directory, letting some scripts in
the lib directory run first.
Then, i cross compile in my mintool directory, there is no such a problem in
dpif.c i reported just now.
But i don't know why.
BTW, my current compile way is that i create a mintool directory, and copy
all the c files related to ovs-dpctl from lib to mintool. I write a Makefile
with cross compile setting, and the separately cross compile the ovs-dpctl
for android.
