  Log:
  Jumbo-commit to enhance 32 bit application support on 64 bit kernels.
  This is good enough to be able to run a RELENG_4 gdb binary against
  a RELENG_4 application, along with various other tools (eg: 4.x gcore).
  We use this at work.
  
  ia32_reg.[ch]: handle the 32 bit register file format, used by ptrace,
          procfs and core dumps.
  procfs_*regs.c: vary the format of proc/XXX/*regs depending on the client
          and target application.
  procfs_map.c: Don't print a 64 bit value to 32 bit consumers, or their
          sscanf fails.  They expect an unsigned long.
  imgact_elf.c: produce a valid 32 bit coredump for 32 bit apps.
  sys_process.c: handle 32 bit consumers debugging 32 bit targets.  Note
          that 64 bit consumers can still debug 32 bit targets.
  
  IA64 has got stubs for ia32_reg.c.
  
  Known limitations: a 5.x/6.x gdb uses get/setcontext(), which isn't
  implemented in the 32/64 wrapper yet.  We also make a tiny patch to
  gdb pacify it over conflicting formats of ld-elf.so.1.
