+will investigate a target architecture by probing hardware, software, libraries
+and compiling and executing code to identify all properties that would be relevant
+to command-line options (VFP, SSE, NEON, ARM vs. Thumb etc), triple settings etc.</p>

+<p>The second stage would be to produce a configuration file (that can be used
+independently of the Host) so that Clang can read it and not need a gazillion
+of command-line options. Such file should be simple JSON / INI or anything that
