Data type question in bcc_elf.c: 236 line

[AlwaysEden]

I used this libelf(https://github.com/WolfgangSt/libelf/tree/master). But It doesn't have GElf_Nhdr data type. The library have following variables. Let me know either bcc project uses other libelf or that is typo.

typedef Elf64_Addr GElf_Addr;
typedef Elf64_Half GElf_Half;
typedef Elf64_Off GElf_Off;
typedef Elf64_Sword GElf_Sword;
typedef Elf64_Word GElf_Word;
typedef Elf64_Sxword GElf_Sxword;
typedef Elf64_Xword GElf_Xword;

typedef Elf64_Ehdr GElf_Ehdr;
typedef Elf64_Phdr GElf_Phdr;
typedef Elf64_Shdr GElf_Shdr;
typedef Elf64_Dyn GElf_Dyn;
typedef Elf64_Rel GElf_Rel;
typedef Elf64_Rela GElf_Rela;
typedef Elf64_Sym GElf_Sym;
