runtime: add support for math package
The math package uses routines written in Go assembly language which LLVM/Clang cannot parse. Additionally, not all instruction sets are supported. Redirect all math functions written in assembly to their Go equivalent. This is not the fastest option, but it gets packages requiring math functions to work.
