Bug#751238: Reopen bug report for switching hwclock-set to use hctosys

Hello!

I'm reopening this bug report regarding using --hctosys in the util-linux
hwclock-set script. The change was proposed for the benefit of arm
systems where RTC drivers are built as modules and when they get loaded
the previous scheme didn't work.

Unfortunately it was reported that the new scheme breaks systems which
(AIUI) the hardware clock is set to local time (and using the new
initramfs-tools 0.118 scheme where time set set up in the initramfs).

As I overheard discussions about building the RTC drivers on ARM into
the kernel I'm going to revert this change in hwclock-set as well.
This should unbreak all versions for now..... 

I'm thus reopening this bug and hope for feedback on how we best handle
this in the future or if it's just ok to have a requirement on RTC drivers
needing to be built-in.

Regards,
Andreas Henriksson
