invalid option: --global-variables

[mdrafiqulrabin]

Hi,

The "csmith --help" shows the following instruction for controlling global variables:

--global-variables | --no-global-variables: enable | disable global variables (enabled by default).

However, "csmith --global-variables" doesn't work, it shows the following error:

$ ./csmith  --global-variables
invalid option --global-variables at: 1

After checking the source code, I found that there is an extra 's' after "--global-variables" in main method of RandomProgramGenerator.cpp file:

if (strcmp (argv[i], "--global-variabless") == 0) {
	CGOptions::global_variables(true);
	continue;
}

Therefore, changing "--global-variabless" to "--global-variables" could be a possible fix.

Thanks.
