Add ccc-syntax/cxx-syntax (darwin-x86)

Wrappers invoked by build system "WITH_SYNTAX_CHECK=1 make ..." in the following format:

    ccc-syntax ARCH LOCAL_CC ...

It calls "clang -fsyntax-only ..." to utilize clang's better diagnostics
before calling "LOCAL_CC ..." for code generation.  ARCH is translated
into "-target XXX" to get proper pre-defined preprocessor symbols/macros,
etc, etc.
