Fix a potential buffer overrun qwhen writing out PE aux entries.
* peXXigen.c (_bfd_XXi_swap_aux_out): Avoid potential buffer
overrun by using sizeof of the destination x_fname field as the
limit for a memcpy.
* coff/internal.h (struct internal_auxent): Fix a couple of typos
in comment describing the x_fname field.
