Hmm..I build my kernel with BTF for bpftrace and this gives me:

...
   CC      init/version.o
   AR      init/built-in.a
   LD      vmlinux.o
   MODPOST vmlinux.symvers

When I revert this it builds fine, just like before. Maybe a missing
requirement or followup fix? I didn't find anything with a quick search.
Using gcc-11, if it matters.
