x86: boot/compressed/vmlinux.lds.S: fix build of bzImage with 64 bit compiler

Jesper reported that he saw following build issue:

> ld:arch/x86/boot/compressed/vmlinux.lds:9: syntax error
> make[2]: *** [arch/x86/boot/compressed/vmlinux] Error 1
> make[1]: *** [arch/x86/boot/compressed/vmlinux] Error 2
> make: *** [bzImage] Error 2

CPP defines the symbol "i386" to "1".
Undefine this to fix it.

[ Impact: build fix with certain tool chains ]
