Currently we use Cmake with arm-elf-gcc as the compiler.
I wanted to try arm-none-eabi toolchain.

I am trying to understand how to go back and forth between arm-elf-gcc
compile and link and arm-none-eabi-gcc compile and link.
I switched the compiler and everything compiles, but linking I get the 
error at the bottom.

I am not clear on the linking. Can anyone tell me how or tell me where 
its explained. I have the Yagarto example, but when I tried going in the 
other direction by changing the makefile from none-eabi to elf - that 
didn't work either. So they must used either a different linker or the 
options are so different you have to change more options... I havn't 
found documentation on linkers differences. Just eabi is more general.

Thanks... arm-none-eabi link error below
