<pre>It is possible to see an ELF with a relocation section but no symbol table, as
not all relocations require symbols. However, llvm-objcopy assumes that there
is a symbol table if it sees a relocation section, and proceeds to try to use
it when loading relocations, resulting in a crash. The offending code is the
initRelocations function.
In the event that the symbol table does not exist (i.e. sh_link is 0), we
should consider emitting an error if any of the relocations have a non-zero
symbol index.</pre>
