The problem appears to be that the INTERP segment has a lot of sections 
besides .interp lumped together:

$ readelf -l script_test_3

Elf file type is EXEC (Executable file)
Entry point 0x10000480
There are 5 program headers, starting at offset 52

Program Headers:
  Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
  INTERP         0x001000 0x10000000 0x10000000 0x0047c 0x0047c R   0x8
      [Requesting program interpreter: /lib/ld-linux.so.2]
  LOAD           0x000000 0x0ffff000 0x0ffff000 0x01c10 0x01c10 R E 0x1000
  LOAD           0x001d00 0x10100d00 0x10100d00 0x00160 0x00160 RW  0x1000
  LOAD           0x001f00 0x10200f00 0x10200f00 0x00000 0x0007c RW  0x1000
  DYNAMIC        0x001d00 0x10100d00 0x10100d00 0x000d0 0x000d0 R   0x4

 Section to Segment mapping:
  Segment Sections...
   
00     .interp .gnu.version_r .gnu.version .hash .dynstr .dynsym .rel.dyn .rel.plt \
.eh_frame_hdr .eh_frame .rodata .note   
01     .interp .gnu.version_r .gnu.version .hash .dynstr .dynsym .rel.dyn .rel.plt \
.eh_frame_hdr .eh_frame .rodata .note .text .plt .text .fini .init   02     .dynamic \
.data .got .jcr .dtors .ctors   03     .bss 
   04     .dynamic 

Now the kernel checks that the segment ends with a NUL, but the .note section 
doesn't:

$ objdump -sj .note script_test_3

script_test_3:     file format elf32-i386
