[Mingw-w64-public] [PATCH] winpthreads/src/dll_math.c: Implement `__divmoddi4()' for GCC 7.

reference to `__divmoddi4'

Here is the 'real' fix for it. Please review.

(I really hate this C-ish code but this way it looks like how 
`__udivdi3` was implemented.)

for GCC

 7.

GCC targeting i686 _may_ generate an external call to the function in
question when divding a 64-bit (DIMode) integer with another one.
Since we are linking against a fake libgcc, this function is not available.
