Can we have below change? Will it work to disable compilation of
event/octeontx2 for FreeBSD? I believe this was done by mistake earlier
as all other octeontx2 drivers are compiled off on platforms other than Linux.

+if not is_linux or not dpdk_conf.get('RTE_ARCH_64')
     build = false

     subdir_done()

Or of this does not work, then we would need to add exception in ABI checking.
Any suggestions how to do this?
