It does look like something is broken though. As you correctly said, the vpp.mk
does distinguish at least between x86 and non-x86 architectures; however, if I
take a clean snapshot from git and use the following commands:
1) make PLATFORM=vpp bootstrap
2) make PLATFORM=vpp build
I get the following error:
make[10]: *** [/root/repos/vpp/build-root/build-vpp_debug-native/dpdk/dpdk
-16.11/mk/internal/rte.compile-pre.mk:140: eal_pci_uio.o] Error 1
make[10]: *** Waiting for unfinished jobs....

#include <x86intrin.h>
It looks like vpp.mk does not correctly waterfall the architecture (i.e.
aarch64) to the local/internal DPDK build system since it tries to build for a
x86 target...
