    PR ld/21529: Use a linker script to limit output with the test case
    
    Complement commit d9409498813c ("Add a testcase for PR ld/21529") and
    use a linker script to prevent an inter-segment gap arranged by the
    default linker script associated with some targets such as `rx-elf':
    
    $ ld -e main -o tmpdir/dump-elf tmpdir/pr21529.o
    $ readelf -l tmpdir/dump-elf
    Elf file type is EXEC (Executable file)
    Entry point 0x10000004
    There are 2 program headers, starting at offset 52
    
    Program Headers:
      Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
      LOAD           0x001000 0x10000000 0x10000000 0x00008 0x00008 R E 0x1000
      LOAD           0x001ffc 0xbffffffc 0xbffffffc 0x00004 0x00004 RW  0x1000
    
     Section to Segment mapping:
      Segment Sections...
       00     .text
       01     .stack
    $
    
    and converted to padding with the use of the binary BFD for output from
    producing unreasonably large files.
