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")
