Test failures on CentOS7 with NetCDF 4.7.0

I am running on CentOS 7:

$ rpm -q centos-release
centos-release-7-6.1810.2.el7.centos.x86_64
$ uname --kernel-name --kernel-release --machine
Linux 3.10.0-957.21.3.el7.x86_64 x86_64

I configured version 1.8.5.0 with:

CPPFLAGS=-I$NETCDF_ROOT/include LDFLAGS=-L$NETCDF_ROOT/lib ./configure

The make succeeds, but make check fails for test_nccmp_61.sh and test_nccmp_63.sh as shown in the log below:
