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     = ?
