  objcopy of archive, element containing an object with a fuzzed section
size far exceeding the element size.  copy_section detects this, but
the temp file is laid out for the large section.  It can take a long
time to write terabytes of sparse file, a waste of time when it will
be deleted.

	* objcopy.c (copy_archive): Don't write element contents after
	bad status result from copy_object.
