#    Define the ARM-specific compilation tools to be used.  (Most NDS
#    developers include devkitPro's "base_rules" and "ds_rules" for these
#    definitions and for the suffix rules, but these files were written
#    without following the conventions used in Make's implicit rules.
#    The implicit rules work just fine for C and C++ files.)
