Hmm, if you only want to support cortex-m3 with your toolchain, you
might be better off configuring gcc to build only for that CPU. Try:
<gcc-sources>/configure --target=arm-none-eabi --with-cpu=cortex-m3 --with-mode=thumb --disable-multilib ...
Your compiler will then be built specifically for cortex-m3 and your
build of newlib should then be optimized specifically for that CPU.
Don't try to use a toolchain built that way for any CPU other than the
one specified; it probably wouldn't work very well.
R.
NB. I haven't actually tried the above, but it should work...
