Make more macro checks ARMv8-M baseline proof

Subject: Make more macro checks ARMv8-M baseline proof

Hi,

After Thomas' patch
(https://sourceware.org/ml/newlib/2016/msg00017.html), it seems that
some changes committed to libgloss are missing in newlib.
I noticed the problem when building a toolchain where GCC is
configured --with-cpu=cortex-m{0,23}.

This small patch brings the necessary changes from libgloss to newlib.
With this, the GCC toolchain build completes.

OK?

Thanks,

Christophe
