[Bug]: Linker flags are ignored when passed to `CreateInterpreter`

[Vipul-Cariappa]

Description of bug

Linker flags are ignored while creating the interpreter. This might also include default search paths. We might need a toolchain or a dummy linker to deduce the necessary linker path and libraries, and explicitly pass them to LoadLibrary and AddSearchPath. Otherwise, fix this issue directly in upstream LLVM.

Once this bug has been fixed, then I might be able to get Emscripten xeus-cpp OpenMP kernels. The previous blocker on these kernels was we only knew of builds of the libomp library which required the pthreads flag. I now believe I have found a recipe which is not reliant on this problematic flag, but we need CreateInterpreter to not ignore linker flags.
