cross compilation?

../openssh-3.1p1/configure --host=mips-linux --build=i686-linux --with-pam
    does not work.

It selects the correct toolchain prefix, but the configure script bails
on cross-compilation.

Attached is a patch that *might* make the right paranoid assumptions,
but I am not positive.

cross compilation?

Can you avoid reforming and just post the required changes you feel
should be made?  It makes it very hard to decide if this is an
acceptable thing to do.
