The DPAA bus driver is defining some macros without prefix.
So it can conflict with other libraries like libbsd:
drivers/bus/dpaa/include/compat.h:53:
error: "__packed" redefined
/usr/include/bsd/sys/cdefs.h:120:
note: this is the location of the previous definition
Fixes: 39f373cf015a ("bus/dpaa: add compatibility and helper macros")

A similar patch was also issued by Jerin a few weeks back:
http://patches.dpdk.org/patch/40597/
There may be conflict while merging.
Whether you take that, or this (preferred):
