binutils: Use file descriptors from make_tempname
The purpose of creating a temporary file securely using mkstemp is defeated if it is closed in make_tempname and reopened later for use; it is as good as using mktemp. Get the file descriptor instead and then use it to create the BFD object. bfd/ * opncls.c (bfd_fdopenw): New function. * bfd-in2.h: Regenerate. binutils/ * bucomm.c (make_tempname): Add argument to return file descriptor. * bucomm.h (make_tempname): Likewise. * ar.c: Include libbfd.h. (write_archive): Adjust for change in make_tempname. Call bfd_fdopenw instead of bfd_openw. * objcopy.c: Include libbfd.h. (copy_file): New argument OFD. Use bfd_fdopenw instead of bfd_openw. (strip_main): Adjust for change in make_tempname and copy_file. (copy_main): Likewise.
