I wrestled with this problem once. The development machine was an i386
host (running redhat Linux) and a Power PC platform (running Monta Vista
Linux).
After many frustrating days of trying to get cross compilation working,
I had an epiphany. I NFS mounted the Monta Vista development environment
and then performed a chroot operation; then the development environment
became my root partition. From that point forward I could configure,
compile, and install the openssh code natively from the power PC
platform. After I completed the installation, I incorporated the shared
object library files and executables into my initial RAM disk.
Of course, it would be nice to have the cross compilation working, but
this dirty trick works should work.
