I am not sure about this patch. I believe there might be a bug in the
powertop configure.ac script. It's doing:

PKG_CHECK_MODULES([NCURSES], [ncursesw ncurses], [LIBS="$LIBS $ncurses_LIBS"], [
        AC_SEARCH_LIBS([delwin], [ncursesw ncurses], [], [
                AC_MSG_ERROR([ncurses is required but was not found])
        ], [])

So, when using PKG_CHECK_MODULES(), it wants both ncursesw and ncurses.
But if that fails, it tests with AC_SEARCH_LIBS(), but in this case, it
is looking for either ncursesw *or* ncurses.

Am I missing something?
