Pull some fixed applied after the release.

Disable the use of code under GPLv3 included in hwclock since v2.30. The
subject was discussed upstream[1] and it was decided that hwclock will
be made GPLv2-only again in v2.36, so do it in advance in Buildroot.

Meanwhile, be warned that all OS images selecting hwclock built with
Buildroot since commit 74235a6854 (util-linux: bump to version 2.30)
contain code under GPLv3, which imposes some technical difficulties to
include in embedded systems. For more information see GPLv3, Section 6,
"Conveying Non-Source Forms", and the definitions of User Product and
Installation Information[2].
