Thanks Ajit/Randy. This removes the error for bnxt on my Fedora 32 system.
Was chatting to David and he suggest if 'static __rte_used' could be
added to the macro as an alternative.
Checked and it [1] is working also. It seems like a cleaner fix for the
specific issue to me. If you have an additional reason to remove the
compile checks, it could be a separate patch or a comment added to the
commit message.

Kevin, Thanks for confirming that the patch solves the issue.
I wanted to do away with the check anyway.
Thanks for suggesting the change though.
