Without this Make variable, Objects.rules does not add font_fnt.o to the build, causing undefined reference to fnt_createfont at link time. Signed-off-by: Acfboy <AcfboyU@outlook.com>
…support for NuttX Build the Nano-X client library, server and (optional) built-in window manager from the bundled Microwindows tree Signed-off-by: Acfboy <AcfboyU@outlook.com>
* Port the nxcalc demo from Microwindows * Connects to the Nano-X server started by examples/nanoxterm * Requires CONFIG_LIBC_FLOATINGPOINT for the result formatting Signed-off-by: Acfboy <AcfboyU@outlook.com>
* Port the nxterm demo from Microwindows * Starts the Nano-X server as a separate task before connecting * Runs an NSH shell instance on a pseudo terminal in the forked child instead of exec /bin/sh (no filesystem binaries in flat builds) Signed-off-by: Acfboy <AcfboyU@outlook.com>

Summary
This PR ports the Nano-X windowing system from Microwindows to NuttX so that X11-style client/server applications can run in a flat build. It contains three logical parts:
graphics/microwindows: build the Nano-X client library and server from the bundled Microwindows tree, with two new Kconfig options:MICROWINDOWS_NANOX: build the Nano-X client library and server.MICROWINDOWS_NANOX_NANOWM: optionally link the Microwindows window manager into the server so the server task draws and decorates windows itself.examples/nanoxcalc: port of the nxcalc demo. It connects to the running Nano-X server and shows a calculator keypad.examples/nanoxterm: port of the nxterm demo. It is a terminal emulator that opens a pseudo terminal, forks, and runs an NSH instance (nsh_consolemain) in the child instead of exec'ing /bin/sh, since flat builds have no filesystem binaries. It starts the Nano-X server as a separate task before connecting, so it can be used as the init entry point: booting sim:nanox opens the nxterm window directly, and typing nanoxcalc in it opens the calculator.Note
There are still some remaining issues, for example, have some problem when running on qemu, so this is just a draft PR. When it is fully ready, I will add the documentation and open it up for review.
