Disable compilation of miniz-sys on WASI

[RReverser]

This aligns build script conditions with all the #[cfg(...)] conditions in that miniz-sys shouldn't be attempted to be compiled on WASI target.

In particular, this previously caused library to fail to compile to wasm32-unknown-wasi target from a Windows host.

error: toolchain 'stable-x86_64-unknown-linux-gnu' does not contain component 'rust-std' for target 'wasm32-unknown-wasi'

Hmm, what did I do wrong?

[bjorn3]

I believe stable doesnt support wasi yet.

[RReverser]

Switched to nightly, but still the same issue:

error: toolchain 'nightly-x86_64-unknown-linux-gnu' does not contain component 'rust-std' for target 'wasm32-unknown-wasi'

[bjorn3]

The target was renamed to wasm32-wasi a few days ago.

[RReverser]

Oh wow. That looks unusual / inconsistent with other target names (at least it's not a triple anymore). Why was it changed?

[bjorn3]

rust-lang/rust#60585

This follows aarch64-linux-android, x86_64-fuchsia, and others in
omitting the vendor field, which has the advantage of aligning with the
multiarch tuple, and of being
less noisy.

@alexcrichton Should be ready now! @bjorn3 thanks for the help!

[RReverser]

@alexcrichton Could you please make a release when you have time?

[bjorn3]

@RReverser I can point wasi-rustc to git until a release has been made. I did the same for measureme.

[RReverser]

@bjorn3 Yeah sure, I know about that workaround, just asked to make sure this is released at some near point in the future :)
