I first produced the issue on my "old" FC32.
Afaics, for FC33 and later, gcc now depends on libatomic and the
problem won't be noticed.
FC32 and before are EOL, but I then reproduced the issue on RHEL 8
(and Intel CI reported it on Centos 8 too).

I tried below diff, and it works for me.
"works" as in net/sfc gets disabled without libatomic installed:
