arc: emsdp: Add more platform-specific compiler options Even though EM SDP is FPGA-based board and different FPGA images (known as .bit-files) are awailable for the board still there's a common subset of options we may rely on for all configs. These are: * Normalizer * Swap instructions * Simple multiplier * Barrel-shifter * Floating-point unit * Shorter instructions (code density) This among other improvements allows to compile code with 64-bit divisions, see [1].
