This should be fixed by this patch - at least for microblaze.
commit 65ba7add0d609bbd035b8d42fafdaf428ac24751
Author: Rob Herring <rob.herr...@calxeda.com>

time: add weak annotation to timer_read_counter declaration
A weak annotation is needed in order to prevent link errors when
get_ticks is overridden. This fixes sandbox build.
