  Log Message:
  -----------
  [libc] Add more robust compile time architecture detection

We may want to restrict the detected platforms to only `x86_64` and `aarch64`.
There are still custom detection in api.td but I don't think we can handle these:
 - config/linux/api.td:205
 - config/linux/api.td:199
