Updated Gentoo image

[Gabriele Svelto]

Hello everybody,
I've uploaded a new version of my Gentoo image for the Ci20. I've
rebuilt everything using the Gentoo profile version 17.0 which means
most of the packages are now built with position-independent code. All
the packages have been updated to current stable versions and the kernel
was updated to version 3.18.132.

I've also enabled the swclock service by default. It's a "software"
clock that records the last time the board was shut down and restores it
during startup. This is useful on boards without a battery-backed RTC
because it guarantees that the clock is always set to a value that is
more recent than any filesystem timestamp (this also applies to the
first boot after flashing the image). This is valuable even when using
NTP to set the board clock because it ensures consistent timestamps
during early boot before NTP can take over and set the correct time.

The image is available here as usual:
