See this commit from ~5 years ago:
17abecfe651c x86: fix up alternatives with lockdep enabled
I was thinking about removing the message back then. Nobody ever
complained: code patching is so fundamental to a properly functioning
Linux kernel that broken binutils would stick out like a sore thumb - and
not just related to lockdep.
So lets remove it.
