Bionic prior to Gingerbread doesn't support sincos*, but upstream GCC
enables sincos optimization for OPTION_BIONIC unconditionally since
4.6. I'd like to propose a new flag -foptimize-sincos for NDK to
maintain backward compatibility.
1. For BIONIC: sincos optimization is disabled by default.

I'd rather think about a way to specify, for all known builtins, whether GCC
should generate calls to such function where
Richard, the target hook (libc_has_function) for what you described is
waiting for a review:
http://gcc.gnu.org/ml/gcc-patches/2013-03/msg01201.html
However, it doesn't have command line options support.

decl_implicit_p isn't whether we've seen
