We have not gotten around to adding support for tail calls  for avr. So nothing
happens. So it is not a bug - but a still a valid feature request.

Can you try using linker relaxation?:
-Wl,--relax

Linker relaxation is implemented in ld for the AVR port, even though the
documentation doesn't say so. IIRC, tail call optimization is implemented in
linker relaxation.
