COMPILER_PATHPath to the compiler to use, in case a specific compiler should be substituted for the one in the system's `PATH` variable. Default is blank (use `PATH` provided compiler).
OPTIMIZATION Optimization level to use when compiling C and C++ source files. Default is `s` (optimize for smallest size).LINKER_RELAXATIONS Boolean, if `Y` linker relaxations will be enabled to slightly reduce the resulting binary's size. Default is `Y`.
JUMP_TABLESBoolean, if `Y` jump tables will be enabled to slightly reduce the resulting binary's size - note that this can cause incorrect jumps if the binary is relocated after compilation, such as for a bootloader. Default is `N`.
OBJDIR Directory to store the intermediate object files, as they are generated from the source files. Default is `obj`.DEBUG_LEVEL Level of the debugging information to generate in the compiled object files. Debug is 2 (medium level debugging information).
