I don't know about 2.95.1 in this situation.
I have successfully cross-built libgcj, for a MIPS target.
I've also successfully built libgcj (not 2.95.1 but a more recent
version) for the PPC (native PPC Linux build).
So I'd imagine it is possible, though some small amount of configure
hacking might be required.

Nope :-(
Luckily, though, it is just like cross-building anything else. Just
configure libgcj the same way you configured your cross-gcc.

Just like gcc.

Nope, configure will do this for you.

`bootstrap' is only used by gcc builds. Don't use it for libgcj.

I don't think libgcj 2.95.1 worked on PPC at all.
