implemented ability to enable -D_FF_RV_EXIST_ in TIF library
It is not clear if this quirk is intentional or not, but TI's production
version of tif_na7_db_{fl,ir}.lib was built without -D_FF_RV_EXIST_,
and as a result, the code that is present in the source for the
TRACEMASK_IN_FFS feature was not compiled in, making the feature unavailable.
The present change makes it possible to re-enable this code (when TIF
libraries are being rebuilt from source rather than used as blobs)
by setting TRACEMASK_IN_FFS=1 on the configure line.
The new code is NOT enabled by default: it is not a change which we can
justify inflicting on our production firmwares.

# TI's original version of the pf_TaskEntry() function in the guts of GPF # does this number once all GPF tasks have entered their main loop: # # TraceMask[0] = 0; # # The effect of this line is that "system" trace output gets disabled; # in particular, "system primitive" requests like querying for existing # TRACECLASS of various entities or for the GPF version elicit no response # whatsoever until one sends a TRACECLASS setting sysprim which restores # the TC_SYSTEM bit in TraceMask[0]. # # In FreeCalypso we consider this clearing of TraceMask[0] to be either # a bug or a misfeature, and we would like to change it. In the case of # the GPF code in question, we do have a copy of frame.c source (the module # where the offending pf_TaskEntry() function is implemented) which we believe # is the same code as what's in the TCS211 version of GPF, but TCS211 is not # set up to recompile any part of GPF from source, and there are other modules # in the same frame_na7_db_ir.lib for which we don't have the original source # (os_*), hence it is easier to do a binary lib patch. # # The present patch is a binary form of: # # -TraceMask[0] = 0; # +TraceMask[0] = TC_SYSTEM; [frame.obj] .text 2ee 10
