This command creates an executable. What you are seeing are the linker 
errors because you have not provided a suitable path to the RTEMS 
libraries for your BSP. To make a library you need to create an object 
file and then create a library containing that file.

I suggest you search the net for ways to do this. A quick google gave me ..

RTEMS is statically linked so we only use static libraries, ie .a files. 
You need to substitute 'mygcc' and 'gcc' with 'i386-rtems4.11-g++' and 
'ar' with 'i386-rtems4.11-ar'.
