can't read "project_name": no such variable (on exit_with_error in exit_if_not_installed)

If goa fails really early due to missing tools

exit_if_not_installed xmllint git find sed make diff tar wget"
    (file "/home/krishna/bin/goa" line 42)

the output does not help to identify the program missing as project_name is not yet defined.

Both following patches fix the issue, while I'd prefer the first if there's not implicit tool dependency in command_line.tcl.

Thanks for the patches! Unfortunately, there is a tool dependency in command_line.tcl. I therefore came up with a modified variant of your second patch (see 48833c9).
