Now that you mention multilib, I noticed that, when building gcc for arm-eabi, cpus like cortex-m3 require you (perhaps that is my mistake) to build it --with-cpu=cortex-m3 --with-mode=thumb (at least), so that newlib's crt0.S gets compiled in thumb-2 mode, so that the right code is generated when using the options -mcpu=cortex-m3 -mthumb. I wonder why crt0.S is not compiled multiple times with all the options required for the cpus and modes supported by the arm-eabi target... I thought that multilib was to ensure that (although I may be wrong about that). Do you know something about this? The crossgcc list seems to be very quiet, and nobody there seems to be willing to give an answer on that.
