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
  MODINFO modules.builtin.modinfo
  GEN     modules.builtin

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.
