#557 CIE augmentation 'S' should be accepted

[Joseph Koshy]

From David Young, via the elftoolchain-developers list.

dwarf_get_fde_list_eh() exits with an error when an object has a CIE with 'S'-augmentation in its .eh_frame section.

Workaround patch:

Committed a slightly different patch in [r3589]. It seems that augment 'S' doesn't have augment data.

Fixed.
