For a binary with SYMTAB STRTAB having different order, like upside down, or
having other section in between. eg.

```
$ readelf -Dd /usr/local/go/bin/go

Dynamic section at offset 0x9e5220 contains 19 entries:
  Tag        Type                         Name/Value
 0x0000000000000004 (HASH)               0xb3c3c0
 0x0000000000000006 (SYMTAB)             0xb3c880
 0x000000000000000b (SYMENT)             24 (bytes)
 0x0000000000000005 (STRTAB)             0xb3c660
 0x000000000000000a (STRSZ)              531 (bytes)
 0x0000000000000007 (RELA)               0xb3bfd8
 0x0000000000000008 (RELASZ)             24 (bytes)
 0x0000000000000009 (RELAENT)            24 (bytes)
 0x0000000000000003 (PLTGOT)             0xde5100
 0x0000000000000015 (DEBUG)              0x0
 0x0000000000000001 (NEEDED)             Shared library: [libpthread.so.0]
 0x0000000000000001 (NEEDED)             Shared library: [libc.so.6]
 0x000000006ffffffe (VERNEED)            0xb3c360
 0x000000006fffffff (VERNEEDNUM)         2
 0x000000006ffffff0 (VERSYM)             0xb3c300
 0x0000000000000014 (PLTREL)             RELA
 0x0000000000000002 (PLTRELSZ)           768 (bytes)
 0x0000000000000017 (JMPREL)             0xb3bff0
 0x0000000000000000 (NULL)               0x0

```

It will mess up the syments (symbol table entry number) calculation.
