[x86] x86 targets without CMOS still build rtc.c despite CONFIG_RTC unset

Hi
I haven't taken the time to fully understand the build mechanism, but
comparing the x86 with other targets, the x86 target doesn't appear to
support CONFIG_RTC. Leaving this unset doesn't prevent
arch/x86/kernel/rtc.c being built into the kernel.
I'm building a linux-2.6.32.16 kernel using OpenWRT trunk for
Bifferboard, an rdc target. The Bifferboard SOC does not have an RTC.
Is this as-designed (i.e. do "all" rdc targets have RTC) or a work-in-progress?
Thanks,
Andy.
