[PATCH] debug: Handle x_flag_var_tracking_* in finish_options [PR102585]

[Martin Liška]

Hello.

The patch sets -1 for x_flag_var_tracking and x_flag_var_tracking_assignments 
similarly
to toplev.c.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Ready to be installed?
Thanks,
Martin
