enable sincos optimization on mingw-w64

Browse Source 
The sincos transformation does not take place on all platforms,
because the libc_has_function target hook disables it by default.

Current mingw-w64's math library supports sincos, sincosl and sincosf,
in 32- and 64-bit modes.  I suppose this has been this way for long.

This patch enables the sincos optimization on this platform.
