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.
