You might need to > edit config/arm/t-arm-elf to enable only the multi-lib that you need. I am sorry if I appear dense, but which multi-lib would I need? Recall that I'm trying to target a cortex-m3, so what exactly do I need for the multi-lib options in t-arm-elf? (And once this is done, how can I effect this change with a configure option, rather than having to edit GCC source?) MULTILIB_OPTIONS = ? MULTILIB_DIRNAMES = ? MULTILIB_EXCEPTIONS = ? MULTILIB_MATCHES = ?
