What if the TU already uses libxsmm_crc32_u64_start for something completely
different? If annobin wants to add its own symbols, they must be not in the
user namespace (so need to include some prefix with . char at best) and
better it should ensure that such symbols aren't exported from shared
libraries or binaries it creates either.
