scons: remove as version check
GNU as 2.31.1 checks if the input and output files are the same: Assembler messages: Fatal error: The input and output files must be distinct The check already does not work for llvm-as which has a different output format. Since it is too hard to maintain the check correctly for all possible assemblers, it is better to just remove it completely.
