It looks like some light skeleton *llinked*.o files left.
   [~/work/bpf-next/tools/testing/selftests/bpf (master)]$ ls *linked1*
   atomics.bpf.llinked1.o             fexit_sleep.bpf.llinked1.o              map_ptr_kern.bpf.llinked1.o       test_ringbuf_map_key.bpf.llinked1.o
   core_kern.bpf.llinked1.o           fexit_test.bpf.llinked1.o               test_ksyms_module.bpf.llinked1.o  test_static_linked1.bpf.o
   core_kern_overflow.bpf.llinked1.o  kfunc_call_test.bpf.llinked1.o          test_ksyms_weak.bpf.llinked1.o    trace_printk.bpf.llinked1.o
   fentry_test.bpf.llinked1.o         kfunc_call_test_subprog.bpf.llinked1.o  test_ringbuf.bpf.llinked1.o       trace_vprintk.bpf.llinked1.o
   [~/work/bpf-next/tools/testing/selftests/bpf (master)]$

All of them from:
   LSKELS := fentry_test.c fexit_test.c fexit_sleep.c atomics.c            \
         trace_printk.c trace_vprintk.c map_ptr_kern.c                   \
         core_kern.c core_kern_overflow.c test_ringbuf.c                 \
         test_ringbuf_map_key.c
   LSKELS_EXTRA := test_ksyms_module.c test_ksyms_weak.c kfunc_call_test.c \
         kfunc_call_test_subprog.c

Considering we only have limited light skeletons, so it should not be a problem. So
