FWIW, I've configured GCC with --target=arm-none-eabi --with-cpu=cortex-m7
--with-mode=thumb and then ran make all-gcc. I think it would work equally well
without the cpu and mode given that these are given on the command line:

arm-none-eabi-gcc -S -mcpu=cortex-m7 -mthumb -O2 foo.c -wrapper gdb,--args
