+Improve the ARM detection to work on Thumb-only architecture
+
+The ARM-specific assembly code doesn't build on Thumb-only
+architectures such as ARMv7-M, but the configure script assumes that
+if the host tuple is arm*, then it can build and use the ARM optimized
+code.
+
+This patch improves the configure.ac detection logic, by building one
+of the instruction of the optimized assembly code, and using this to
+decide whether or not the optimizations should be enabled.
