We are supposed to use pkg-config to link DPDK.
Does the problem appear between a DPDK compiled with meson
and an application linked with pkg-config information?

If the problem really needs to be solved,
the EAL patch (first of this series) needs to be discussed
and reviewed carefully. I don't imagine it being done in 20.05.
