If you manage to operate timer/counter 2 asynchronously from a
32 kHz crystal, avr-libc will support power-save mode for your
ATtiny85. ;-)

So yes, it's a bug in avr-libc, but a very minor one.  The difference
between power-down and power-save mode is that in the latter,
timer/counter 2 will remain operational, with the intention that it
can be clocked asynchronously from a 32 kHz crystal.  Obviously, for
hardware that does not support this modus of operation, power-save
mode makes no sense.
