 390 #   SUFFIX Override the default suffix for the output file
 391 #   TOOLCHAIN Name of toolchain setup to use. Defaults to TOOLCHAIN_DEFAULT.
 392 #   SRC one or more directory roots to scan for C/C++ files.
 393 #   CFLAGS the compiler flags to be used, used both for C and C++.
 394 #   CXXFLAGS the compiler flags to be used for c++, if set overrides CFLAGS.
 395 #   LDFLAGS the linker flags to be used, used both for C and C++.
 396 #   LIBS the libraries to link to
 397 #   ARFLAGS the archiver flags to be used
 398 #   OBJECT_DIR the directory where we store the object files
 399 #   OUTPUT_DIR the directory where the resulting binary is put
 400 #   INCLUDES only pick source from these directories
 401 #   EXCLUDES do not pick source from these directories

 406 #   EXTRA_OBJECT_FILES List of extra object files to include when linking
 407 #   EXTRA_DEPS List of extra dependencies to be added to each compiled file
 408 #   VERSIONINFO_RESOURCE Input file for RC. Setting this implies that RC will be run

 412 #   REORDER reorder file
 413 #   USE_MAPFILE_FOR_SYMBOLS if true and this is a STATIC_BUILD, just copy the

 422 #       toolchain when compiling C++ code
 423 #   STRIP_SYMBOLS Set to false to override global strip policy and always leave

 425 #   DEBUG_SYMBOLS Set to false to disable generation of debug symbols
