builtins: Allow building windows arm functions for mingw
When building with clang/LLVM in MSVC mode, the msvcrt libraries contain
these functions.
When building in a mingw environment, we need to provide them somehow,
e.g. via compiler-rt.
The aeabi divmod functions work in the same way as the corresponding
__rt_*div* functions for windows, but their parameters are swapped.
The functions for converting float to integer and vice versa are the
same as their aeabi equivalents, only with different function names.
