arm: fix build on Thumb-only architectures

Building tinymembench for ARM Cortex-M currently fails, because the
arm-neon.S file contains ARM code that doesn't build on Thumb-only
architectures. To account for this and fix the build for Cortex-M,
this patch adjusts the compile time condition to also verify that the
architecture supports the ARM instruction set, by testing the
__ARM_ARCH_ISA_ARM compiler define.
