+Do not make symbols hidden on Blackfin
+The libselinux logic to hide internal symbols from the DSO doesn't
+work properly on Blackfin due to the USER_LABEL_PREFIX not being
+handled properly. A real fix is not that simple, so this patch simply
+disables the internal symbol hiding mechanism. This means that those
+symbols are visible in the final DSO, which is not a problem for
+proper execution, it just isn't as clean.
