Make more macro checks ARMv8-M baseline proof.
Commit 69f4c4029183fb26d2fcae00790881620c1978a3 improved most
macro checks to be ARMv8-M baseline proof, but missed a few
occurrences which otherwise fail to build when using a CPU setting
such as cortex-m0 or cortex-m23. This patch brings the same
changes as the ones that were committed to libgloss at that time.
