Issues building on Apple M1 chips

[chrux]

Hello,

I tried building this in an Apple Silicon chip and got this error

Compiling tokio-native-tls v0.3.0
The following warnings were emitted during compilation:

warning: clang: error: the clang compiler does not support '-march=native'
warning: clang: error: the clang compiler does not support '-march=native'

error: failed to run custom build command for `libwebp-sys v0.6.0`

Caused by:
  process didn't exit successfully: `/Users/christian/Developer/cmnh/imageflow/target/release/build/libwebp-sys-647a8e6d13b44bda/build-script-build` (exit status: 1)

Any workaround or indication about how to build/run this on this arch. Thanks

Could you provide the version of CLANG used? it may be helpful to upgrade CLANG.
