Compiler flags will be generated by the pkg-config provided by DPDK - the
CPU flags exceed the features of the xgene CPU.

That said, in the context of compiling a DPDK enabled version of OVS for
arm64 for general consumption, having a practical baseline for CPU features
that are actually useful to arm64 users is important.

Canonical have some fairly earlier arm64 hardware in the Ubuntu build
infrastructure which is probably below the sensible baseline for DPDK
support.
