abg-corpus.cc: report architecture discrepancies

If there ever is a discrepancy between the architectures of the
corpuses of a corpus group, libabigail will just abort with an
assertion, if enabled. However, this is a case of invalid input and
the cause should be reported to the user.

	* src/abg-corpus.cc (corpus_group::add_corpus): Report
	architecture discrepancies.
