util/build-gnu.sh reword error w/o gnu coreutils

Browse source 
For a new contributor, the message given by `utils/build-gnu.sh` is
fairly confusing - it starts with several lines of noise (showing
variables that are set in the script) followed by an error about missing
"GNU" and a `git` command string.

This commit changes the script to explicitly instruct the user to run
the `git clone` command. Since the GNU coreutils repository is probably
missing for new developers, this error is shown if the repository is
missing without including VARIABLE=value lines that are not actionable
yet.
