/* 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. */
