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.
