* aoutx.h (NAME(aout,find_nearest_line)): Handle the case 

of two N_SO stabs, one for directory, and one for filename.

	* bfd-in.h (print_vma):  Factor out duplicate definition.

	Exit a little more gracefully when malloc returns NULL.
	* libbfd.c: New function bfd_xmalloc (malloc wrapper).
	* opncls.c, syms.c, bout.c, aoutx.h:  Replace malloc by bfd_xmalloc.
	* libbfd.h: Rre-generated due to libbfd.c update.

This function closes a BFD. It differs from @code{bfd_close} since it
does not complete any pending operations. This routine would be used
if the application had just used BFD for swapping and didn't want to
use any of the writing code.
If the created file is executable, then @code{chmod} is called to mark
it as such.
All memory attached to the BFD's obstacks is released.
@code{true} is returned if all is ok, otherwise @code{false}.
