reloc_upper_bound size calculations
Section reloc_count is an unsigned int. Adding one for a NULL terminator to an array of arelent pointers can wrap the count to zero. Avoid that by doing the addition as longs. * coffgen.c (coff_get_reloc_upper_bound): Don't overflow unsigned int expression. * elf.c (_bfd_elf_get_reloc_upper_bound): Likewise. * elf64-sparc.c (elf64_sparc_get_reloc_upper_bound): Likewise. * mach-o.c (bfd_mach_o_get_reloc_upper_bound): Likewise. * vms-alpha.c (alpha_vms_get_reloc_upper_bound): Likewise.
