Is our TinyCC build on Windows setting `-march` correctly?

[Jarred-Sumner]

Where are we setting C flags when building TinyCC? How are we making sure that baseline builds are working correctly with TinyCC?

https://github.com/oven-sh/bun/blob/830af23742c957296db4cd7a5ffe25c1bac143db/scripts/build-tinycc.ps1#L20-L25

It feels highly suspicious that so many of the "Illegal instruction" errors include a stack trace that points to TinyCC. Either something is going wrong while generating the stacktrace, or something is wrong with the TinyCC build.
