[ELF.h] - Check the case when e_shstrndx=SHN_XINDEX, but the corresponding sh_link is broken.
When e_shstrndx is equal to SHN_XINDEX,
the index of the section string table section should
be taken from the sh_link field of the section
header at index 0.
If sh_link is broken, e.g. contains an index that is
larger than number of sections, then error is reported.
This error message was untested before.
