not really a bug but somewhat odd : checking compiler /usr/local/bin/gcc8 ... no, mpn_lshift_com

Dear gmp/mpfr folks :
On a ppc64 FreeBSD 13.0-CURRENT r350103 boxen I am getting a compile
error over and over. I have not seen this before anywhere. I am
wondering if my CFLAGS were the issue and so I simply removed them from
the equation :
