configs/* except classic: rebuild tif_na7_db_{fl,ir} from source The purpose of this change is to allow a TRACEMASK_IN_FFS=1 setting given on the configure line to have effect; all configs except classic are included because this feature setting is orthogonal to the choice of G23M PS version and other config choices. (The classic config is an exception because its very purpose is to preserve a reference config with all of the original blobs.) Note that even though we are switching these TIF libraries from blobs to recompilation from source in all configs, our source for these libs compiles into a perfect match to the original blobs in the current default TRACEMASK_IN_FFS=0 configuration, hence there is no effective change beyond the unfortunate small increase in compilation times.
