* aoutx.h (NAME(aout,canonicalize_reloc)): Don't error out if 

section->relocation is NULL; malloc might have returned NULL when
	given a zero size if there were no relocations.
	* bout.c (b_out_canonicalize_reloc): Likewise.
	* coffcode.h (coff_canonicalize_reloc): Likewise.
	* ecoff.c (ecoff_canonicalize_reloc): Likewise.
	* elfcode.h (elf_canonicalize_reloc): Likewise.
	* mipsbsd.c (MY(canonicalize_reloc)): Likewise.
	* i386lynx.c (NAME(lynx,canonicalize_reloc)): Likewise.
	* nlmcode.h (nlm_canonicalize_reloc): Likewise.
	* som.c (som_canonicalize_reloc): Likewise.
	* hp300hpux.c (MY(slurp_reloc_table)): Likewise.  Also, if malloc
	returns NULL, don't report an error if we asked for zero bytes.
	* i386lynx.c (NAME(lynx,slurp_reloc_table)): If malloc returns
	NULL, don't report an error if we asked for zero bytes.
	* nlmcode.h (nlm_slurp_reloc_fixups): Likewise.
