sshd on Nios II uClinux with buildroot

I built the ssh and sshd with buidlroot and uClinux-dist-20051110.

But I didn't run them yet. (I don't have any boards with Ethernet)

1. follow tschmelcher's sshd guide, build openssl in buildroot.

2. build zlib in buildroot, it may fail in so, but just ignore it.

3. apply the uClinux-dist.diff as in build script.

edit uClinux-dist/vendors/Altera/nios2nommu/config.arch, add "-lcrypt -lutil" to LDPATH for apps.

touch uClinux-dist/vendors/Altera/nios2nommu/inittab

4. build ssh and sshd in uClinux-dist, but DON'T use the cross patches in tschmelcher's sshd guide.

make menuconfig,make subdirs,make romfs.
