Mostly unrelated to your original question:

Please remove this.

(This is of course 100% ok, but if you are unexperienced 
I would strongly recommend not to use it, it generally 
has theoretical problems and the gain for you as a 
user is not completely clear to me, in combination with 
"--prefix=/usr", I personally consider it highly 
dangerous and would not use it on my system.)

This makes no sense in the configure line you posted.

(I would even recommend to remove these two.)

This is the default, please remove it.

> --enable-postproc

This also makes no sense.

I suspect you do not need / want this.

I may miss something but I suspect you should remove 
those (at least some of them).
