Confirmed. Configuring with:

    ./configure --host=ppc-unknown-linux-gnu --build=ppc-unknown-linux-gnu \
              --target=ppc-unknown-linux-gnu

passed all tests.

I suspect that this is because you and I are both running 32 bit user space
on a 64 bit kernel. I'm running Debian Testing.

I've seen this problem too, with same situation (64 kernel, 32
userspace). Looks like configure is wrong about the target?

Best regards,

Actually, I'm not sure.

Even though my debian PPC machine has a 64 bit kernel with a 
32 bit userspace, it does support 64 bit programs. The distro
supplied C compiler by default generates 32 bit binaries but
if I pass it -m64 on the command line will generate 64 bit
binaries.

It would be however be nice if the configure could do the right
thing on systems with 64 bit kernel and 32 bit userspace.

Cheers,
Erik
