TCC already has that flag: -fcommon

Also, your patch does wrong things:

Example:

foo.c:
    int xxx = 12;
    int main() { printf("--> %d\n", xxx); return 0; }
bar.c:
    int xxx = 34;
tcc foo.c bar.c && ./a.out
    --> 12

This is wrong.  Result must be "error: xxx defined twice"

Another example:

foo.c:
    int xxx;
    int main() { printf("--> %d\n", xxx); return 0; }
bar.c:
    int xxx = 34;
tcc foo.c bar.c && ./a.out
    --> 0

Wrong too.  Result must be "--> 34"
