In fact I'm trying to build a compiler that I will use to build a new
operating system, so it should not generate Linux code (that's why I choose
the coff format I believe it is a generic format). As a standard library,
I'd like to build glibc (or newlib if it is better suited ?), also for a ARM
platform.
