cksum: port to Apple LLVM version 10.0.0

This compiler lacks support for the x86-64 VPCLMULQDQ instruction;
compiles fail with "error: invalid cpu feature string for builtin".
Problem reported by Peter Dyballa, and fix suggested by
Pádraig Brady <https://bugs.gnu.org/78562#8>.
* configure.ac (USE_AVX512_CRC32):
Also check that __builtin_cpu_supports ("vpclmulqdq") compiles.
