just a wild guess... but could it be because gcc-cross and
gcc-cross-initial both start with 'gcc-cross', hence the regexp in this new
commit is catching them twice? i am referring to this:

-        if f in self.appendlist:
-            return self.appendlist[f]
-        return []
+        for bbappend in self.appendlist:
+            if bbappend in f or ('%' in bbappend and
bbappend.startswith(f[:bbappend.index('%')])):
+                self.appliedappendlist.append(bbappend)
+                for filename in self.appendlist[bbappend]:
+                    filelist.append(filename)
