Add Metalshark's patches:

Browse Source 
*) Add -march=pentium-m if compiling finit or finit-mod (as the target will
   be an eeepc).
*) Add a -DNO_HCTOSYS make option that omits the first /sbin/hwclock if the
   user has enabled CONFIG_RTC_HCTOSYS in the kernel.
*) Add a -DDIRECTISA make option to append –directisa to /sbin/hwclock lines
   if the user has disabled CONFIG_GENRTC and enabled CONFIG_RTC but not
   enabled CONFIG_HPET_TIMER and CONFIG_HPET_RTC_IRQ.
