[ECOS] problem with am_31 sim + patch

[ECOS] problem with am_31 sim + patch

[Sebastian Fischmeister]

Hello.

  I faced problems with the linker script of the am_31 and applied a bugfix
that was on the mailing list for the target sh*. Below you will find the
patch for the files.

However, I still cannot run the simple hello world example. Below there is
the output from the gdb session. Hopefully, somebody can give me a clue.
thanks a lot.
