Updated cli arguments to meet up comming changes.
Loading of MSCOFF library instead of OMF for 32 bit build if using MSVC.
Modified the linker to reflect MSCOFF support is not only for 64 bit builds.
Changed error message to reflect that we no longer only generate or use 64bit MSCOFF binaries
May or may not be needed. But I believe it is.
Checking now if we are using Microsoft tool chain instead of if we are 64bit.
Replacing checks of Win64 with checks for if we are using Microsoft tool chain. I am not 100% sure this is the best though.
