Add "WITH_SYNTAX_CHECK=1 make ..."

The new option WITH_SYNTAX_CHECK=1 instructs build system to invoke
"clang -fsyntax-only" to utilize clang's better diagnostics before calling
LOCAL_CC/LOCAL_CXX for code generation.  The compilation time is slightly
longer, and the generated object file should be the same as w/o WITH_SYNTAX_CHECK

Project use lots of GCC extensions (eg. nested function) not supported
by clang may opt out by adding LOCAL_NO_SYNTAX_CHECK:=true
