FWIW, make check-gcc RUNTESTFLAGS='--target_board=unix/-mtbm execute.exp' shows 
204 failures on a host that does not support TBM, so the extension is being 
used.  A browse through exactly one of these used only bextr.  Running the same 
tests with dejagnu using qemu-x86_64 -cpu qemu64,+tbm shows zero failures.
