[gold patch RFC]: Release unused external member of thin archive

[Ian Lance Taylor]

Hi Cary, does this patch look correct to you?  It explicitly unlocks an
external member of a thin archive if the member is not used.  That
avoids locking up the descriptor and possibly eventually running out of
descriptors.  I don't have a test case, but it seems like the right
thing.  If this looks right to you, I'll commit it.

	* archive.cc (Archive::include_member): Unlock an external member
	of a thin archive.  Don't bother to delete an object we know is
	NULL.
