Current w64-mingw's math library supports sincos, sincosl and sincosf, in 32- and 64-bit modes. I suppose this has been this way for long, also with mingw32 and cygwin. This patch enables the sincos optimization on these platforms. Tested with builds targeting mingw-w64, also regstrapped along with other patches on x86_64-linux-gnu.
