This appears to be related to cross compiling VPP. vppapigen is built for the cross target, but then run on the host as part of the build.
Can someone who is familiar with the build system confirm? If so, is it worth fixing a cross build such that vppapigen is compiled for host target and run on host target when cross compiling for the cross target?

I do it on amd64 platform using qemu static library for qemu-aarch64-static for emulation of arm64 instructions.
