Thank you for all the hints/insights/helps on identifying the strange testcases failures. It turns out to be missing a symbolic link inside /lib/arm-linux-gnueabi/ on libgcc_s.so, which both clang-3.3 and clang-3.2 use for linking.
Now, the 3 strange problems are all gone :-) I am running a clean build/test for POCL-0.8rc7 now.
