  /* R_BPF_64_NODYLD32 is not used by GNU tools - but it is generated by LLVM.
     We provide an entry here so that tools like strip can safely handle BPF
     binaries generated by other tools.
     R_BPF_64_NODYLD32 should be fixed at linker like a R_BPF_64_ABS32.
     The difference to ABS32 is that LLVM execution engine does not resolve
     R_BPF_64_NODYLD32 relocations.  */
