Prior to this commit, the command "scripts/objdiff record path/to/*.o"
disassembles the given object into ".tmp_objdiff/path/to/*.o" file.
The problem here is that recorded disassemblies are lost if we run
"make clean" because "make clean" removes all the *.o files.
Disassembled code should be dumped into *.dis instead of *.o file.
