The tx39 tools output dwarf-2 debugging information by default, not stabs
(which would be when the mdebug section is used). There should be no
.mdebug section - in fact we explicitly remove it for the tx39 because we
found sometimes GDB got confused when both stabs and dwarf-2 debug
information was in the same executable.

Which gcc and gdb versions are you using? And did you compile hello.exe
(and your app) with -g and not -ggdb or -gstabs or anything? If you just
used the makefile, then that would mean just -g.
