Using target `x86_64-pc-windows-gnu` still tries to link in `msvcrt`

[doawoo]

I have had a lot of success targeting Linux and macOS machines with this. However I'm running into a puzzling issue, it seems that Rust really wants to link msvcrt, even when the command I'm specifying is:

cargo zigbuild --target x86_64-pc-windows-gnu

It complains about not being able to locate the library.

  = note: error: unable to find dynamic system library 'msvcrt' using strategy 'paths_first'. searched paths:

Does this flag need to be filtered out in the linker argument processing step? Re-running the long command that's spat out, and then removing the -lmsvcrt results in the build proceeding further until it hits the temp files that no longer exist post-build.
