Although that looks like a win, I keep coming back to the question, why 
should Gnulib have pclmul enabled while coreutils does not? More 
generally, why does coreutils bother to check for whether pclmul is 
enabled? Can't it rely on Gnulib's determination?

Gnulib and coreutils check for pclmul slightly differently, but I don't 
see why there should be a difference.
