* Makerules (lib): Depend on lib-noranlib.

	(lib-noranlib): Depend on $(install-lib) in objdir.
	(common-mostlyclean): Remove $(install-lib) and stub-$(subdir)
	from objdir.  Don't remove TAGS; it comes in the distribution.

	* malloc/malloc.c (morecore): Save errno around call to
 	_realloc_internal.  Don't account for the additional new blocks of
 	the info table itself when choosing the new table size for the
 	first crack; if it succeeds, the new blocks will have been found
 	in existing free space already described by the existing info
 	table.
