* 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.
