Cross compiling with the i386-elf toolchain?

[Paul Guyot]

Cross toolchains such as MacPort's i386-elf are target agnostic. They  
rely on a minimum runtime glue code (in crt0.o file). This library  
highly depends on the kind of target you are targetting. You can  
either compile/write one yourself in assembly language (that's the  
approach for targets with open-source crt0 file) or use one from the  
SDK of the platform you are targetting.
