2.2.18pre Pentium IV bug fix

Alan,

2.2.18pre's include/asm-i386/elf.h is currently broken for the
Pentium IV (out of bounds array indexing error).
Since ELF_PLATFORM is identical to system_utsname.machine, the
patch below simply tosses ELF_PLATFORM's broken name generation
code and uses system_utsname.machine instead.
There is no behavioural change for P6 and lesser CPUs.
