Build instuctions:
At the time of 'make', you must have a valid Traveler configuration instantiated
in the NuttX directory. This is because the build will depend on certain
configurations (such as color format).
1. cd nuttx/tools
./configure.sh sim/traveler (for example)
2. cd ..
tools/sethost.sh -w or -l
make context
Prepare some header files. This is necessary because we must use ALL of the
toolchain header files except for a few files from nuttx (for example,
config.h).
3. cd apps/graphics/traveler/tools/nuttx
4. make TOPDIR=<nuttx directory>
Then you can build the world library:
5. cd apps/graphics/traveler/tools/libwld
6a. make
If you want to create a debug-able version of the library, do:
6b. make DEBUG_LEVEL=1
