I didn't checked the latest fs-UAE dev builds but dependencies are all available.
Fs-UAE is available for arm for a long time (2years for pandora).

Problem is that the last ppc additions haven't been commited yet into that branch.
This could be solved If there is really interest.
I would donate a bigger sum as soon xu3 like devices are availble for less than 100€.
Than ppc emulation starts to make sense.
