improve modalias building
For one, there's no point in the respective pieces to be rebuilt unconditionally on each and every rebuild. Second there's no need to invent a custom rule for generating the .s file from the .c source - we can simply use the generic rule here. And finally, $(obj) should be used to refer to files in the build tree (rather than spelling out the subdirectory).
