* configure.ac: Invoke AC_CHECK_SIZEOF(int).
* configure: Regenerate.
* coffgen.c (coff_get_reloc_upper_bound): Replace gcc diagnostic
workaround with SIZEOF_LONG vs. SIZEOF_INT check.
* elf.c (_bfd_elf_get_reloc_upper_bound): Likewise.
* elf64-sparc.c (elf64_sparc_get_reloc_upper_bound): Likewise.
