In the function load_asl(), we will use iasl to convert aml file to
asl source code file.

I copy the iasl file from /tmp/ to another directory, so I can use
old version and new version iasl to investigate.

Here is the different:
@@ -18,7 +18,7 @@
  *     Compiler ID      "BXPC"
  *     Compiler Version 0x00000001 (1)
  */
-DefinitionBlock ("t1.aml", "DSDT", 1, "BOCHS ", "BXPCDSDT", 0x00000001)
+DefinitionBlock ("", "DSDT", 1, "BOCHS ", "BXPCDSDT", 0x00000001)
 {
     Scope (\)
     {

The newest iasl does't output the aml filename: "tl.aml"

In the function normalize_asl(): we hope the output contains the aml filename...
