This looks good. What exactly do you observe with the "touch test app"
in development tools?

I'm still not convinced with tslib path (unless there is some specific
reason to build this). The libc is not required to be replaced.
Instead use your EABI toolchain to build the ts_calibrate tool, run
the configure command as given above and see the final phase of
linking and verify if the libraries (libc also) get linked statically.
