Hi,

here is V3 of the patch. Changes from V2:

- removed IBM copyright
- removed GETAUXVAL check in favor of the already provided check
- moved runtime selection code from pg_crc32c_s390x_choose.c to
pg_crc32c_s390x.c and removed _choose.c file
- removed the config time compiler check and let the buildsystem fall
back to sb8
- changed buffer limit back to 32 bytes before calling s390x specific
implementation
