Vladimír Čunát noticed gdb-12.1 build failure on 32-bit systems with
-Werror=format-security

Build of gdb on i686-linux-gnu is in --enable-64-bit-bfd mode:

    sim/../../sim/cris/sim-if.c:576:28:
        error: format '%lx' expects argument of type 'long unsigned int',
        but argument 4 has type 'bfd_size_type' {aka 'long long unsigned int'}
[-Werror=format=]
      576 |       sim_do_commandf (sd, "memory region 0x%" BFD_VMA_FMT
"x,0x%lx",
          |                            ^~~~~~~~~~~~~~~~~~~
      577 |          interp_load_addr, interpsiz);
          |                            ~~~~~~~~~
          |                            |
          |                            bfd_size_type {aka long long unsigned
int}
