The below patch adds a new preprocessor define for the device name (__AVR_DEVICE_NAME__) that was passed to the compiler.
While the device name macro (say __AVR_ATmega128__) can be used to check for a specific device, there is no way right now for code to get the device name it is being compiled against (without checking for every possible device). This patch is groundwork for embedding device information in a note section (see binutils ml discussion https://www.sourceware.org/ml/binutils/2014-07/msg00146.html), so that utilities that operate on the ELF file do not have to hardcode device information themselves. If ok, could someone apply please? I don't have commit access.
