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).
