32 bits architectures do not support u64 division, so the macro
DIV_ROUND_CLOSEST is not adequate as the compiler will replace the
call to an unexisting function for the platform, leading to an
unresolved symbols.
Fix this by using the compatible macros:
DIV64_U64_ROUND_CLOSEST and DIV_ROUND_CLOSEST_ULL.
