Problem compiling CPPUtest for microblaze

[SpaceShawn]

It should be possible to compile CPPUTest for Microblaze by specifying the architecture during configure

First you need to update config.sub and config.guess as such:

$ cp /usr/share/misc/config.{sub,guess} /path/to/cpputest/

Then run configure

$ ./configure --host ./configure --host=microblazeel-xilinx-linux-gnu

However, when we run make there are issues:

$ make
make  all-am
