Never, NEVER do -I/usr/include.  You are attempting to tell the compiler to use
your HOST system's include files when building software for a target.  This is
an incorrect development practice.  You should be sure to use both headers and
libraries built for the appropriate target architecture.

This will not work.  The random RPM you have downloaded is for a host system,
and not a cross development system.  You may be able to play some games with it
to get the pieces you want out.. but it's still not the right answer as it was
built with a different compiler and may be linked to other random libraries.

You shouldn't.  The proper method is to build ncurses in a cross-development
environment and install the components into the appropriate directories.  (The
"appropriate directories" varies based on product and what you have built.)
