Of course, you are right. They are built but not installed. Fixed.

Well, this leads to some hardcoded check of architecture into the
dpdk.mk. I don't like such approach. Would you instead accept the
following (temporary) patch into Buildroot as a solution for this?
http://dpdk.org/ml/archives/dev/2016-April/037577.html
I will remove it with the next DPDK release (when it's in the
mainline). I've tested and it builds successfully for both ABI and
EABIhf.

Sure, I will resend after I solve the ARM ABI issue.
