You need to install cross toolchain.  In the log:

I think that your system doesn't have cross toolchain.

I don't know why configure didn't fail in this situation.  Perhaps, it
assumed that standard 'gcc' should have capability to compile for the
host powerpc-unknown-linux-gnu.

I don't have enough knowledge of current cross toolchain for Debian,
but it seems that there are packages by Ubuntu:

    https://launchpad.net/ubuntu/+source/powerpc-cross-toolchain-base
    https://launchpad.net/ubuntu/+source/gcc-defaults-powerpc-cross
    https://launchpad.net/ubuntu/+source/gcc-4.9-powerpc-cross
    https://launchpad.net/ubuntu/+source/binutils-powerpc-cross

I haven't tried those packages, though.  Just FYI.
