I'll answer myself, since I just found the solution to the problem - with help from 'kos_tom' at #uclibc on freenode.
The problem is caused by a missing 'CONFIG_FUTEX=y' in the defconfig for our target. The system we're developing is based on the Adder port by Scott Wood, which is also missing this, so a patch should be committed for this and possible other 8xx targets as well.
