Doesn't really matter much. Since the library is pre-compiled, you
cannot map it to the user's -Ox compiler option anyway.
As Johann already explained, most AVR users care for saved flash
and RAM more than for saving a few CPU cycles.
Skimming generated code, IMO modules like vfprintf should be
compiled with -mcall-prologues; at least the versions that
supply float support (as many float functions use call-prologues
anyway).
