Subject: [openrisc] Cross toolchain on sparc.
Hi,
I was able to setup a GNU cross toolchain for or32 on my sparc thanks
the the instructions on the openrisc site. However, to get the simulator
to link and run I needed the following changes. If you apply this
patch remember to run automake, autoheader and autoconf.
