How to disable usage of VPCLMULQDQ

Hi All,

DPDKv22.11

My build machine supports VPCLMULQDQ instruction, but the machine I run
DPDK on doesn't support it, is there a way to force the build system not to
use this instruction?

Right now, I added this line at the beginning of config/x86/meson.build:
machine_args += '-mno-vpclmulqdq'

But, it would have been nice if there was a build config to do this.

Best Regards,
Oleksandr
