Next problem:

localhost / # ssh -f -N [email protected] -L 2222:linux.test.com:22
ssh: Warning: failed creating //.ssh: Read-only file system

Host 'proxy.test.com' is not in the trusted hosts file.
(fingerprint md5 e4:51:30:dc:c5:9a:fc:51:29:36:18:4d:4e:30:bd:67)
Do you want to continue connecting? (y/n)

Maybe I need to rebuild Dropbear SSH to use another directory for .ssh? Maybe put it in /data/.ssh ?

You would need to put it somewhere and give it permissions to read/write (since it's a command line only app, I'm not sure where short of mounting your drive [maybe /data/local/tmp] or putting on your sdcard. ".ssh" is just the directory your keys are normally stored if you're using ssh key login instead of passwords [much safer than using passwords]).

However, it still looks like it's connecting regardless of that.

Yep, probably missing libraries. At worse, compile it with something other than NDK, that might help.
