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. newlib: * libc/sys/arm/crt0.S: Use THUMB1_ONLY rather than __ARM_ARCH_6M__.
