    Make timestamp collection conditional in hardwaremain.c
    
    Otherwise it breaks 486 boards without RDTSC, ending with
    exception 6.
    
    It ends like this on bifferboard:
    
    Jumping to image.
    Unexpected Exception: 6 @ 10:001007e3 - Halting
    Code: 0 eflags: 00000016
    eax: 001001fe ebx: 00100118 ecx: 00000000 edx: 00108e00
    edi: 0010aaf8 esi: 00000000 ebp: 00117ff4 esp: 00117fd8
    
    Please keep in mind 486, dont use rdtsc/cpuid in generic code, or if you do make sure make it non-default option.
