[PATCH 03/12] objdump, readelf: Report errors from CTF archive iteration

[Nick Alcock]

We were failing to report errors from ctf_archive_iter, which results in
silent early termination if (for example) one CTF archive member in a
.ctf section is corrupted and cannot be opened.  Report the error in the
usual fashion instead.

	* objdump.c (dump_ctf): Report errors from ctf_archive_iter.
	* readelf.c (dump_section_as_ctf): Likewise.
