Toke Høiland-Jørgensen 9fc0420864 libbpf: Don't crash on object files with no symbol tables ...

[ Upstream commit 03e601f48b ]

If libbpf encounters an ELF file that has been stripped of its symbol
table, it will crash in bpf_object__add_programs() when trying to
dereference the obj->efile.symbols pointer.

Fix this by erroring out of bpf_object__elf_collect() if it is not able
able to find the symbol table.

v2:
  - Move check into bpf_object__elf_collect() and add nice error message
