[PATCH] driver: drop flag_var_tracking_assignments flag

[Martin Liška]

The revision r13-259-g76db543db88727 moved a condition from one
file to another, but now we do not drop x_flag_var_tracking_assignments
as it was done before the mentioned revision.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Ready to be installed?
Thanks,
Martin
