More potential problems:

aout-adobe.c:#define aout_32_close_and_cleanup
aout_32_bfd_free_cached_info
aout-tic30.c:#define MY_close_and_cleanup MY_bfd_free_cached_info
bout.c:#define aout_32_close_and_cleanup
aout_32_bfd_free_cached_info
coff-sh.c:#define coff_small_close_and_cleanup \
elf64-aarch64.c:#define bfd_elf64_close_and_cleanup             \
elf64-ia64-vms.c:#define bfd_elf64_close_and_cleanup elf64_vms_close_and_cleanup
elfxx-target.h:#define	bfd_elfNN_close_and_cleanup _bfd_elf_close_and_cleanup
i386os9k.c:#define aout_32_close_and_cleanup aout_32_bfd_free_cached_info
som.c:#define	som_close_and_cleanup		        som_bfd_free_cached_info
vms-alpha.c:#define alpha_vms_close_and_cleanup	   vms_close_and_cleanup

We need to make sure that all of them call  _bfd_generic_close_and_cleanup
at the end.
