ci: Fix Android breakage

[notgull]

Uses a workaround for cross-rs/cross#1128 and rust-lang/rust#103673

[taiki-e]

We maybe also need to update cross version to the latest.

From:

polling/.github/workflows/ci.yml

Lines 79 to 82 in e10c7e8

	uses: taiki-e/install-action@v2
	with:
	# https://github.com/cross-rs/cross/issues/724
	tool: cross@0.2.1

To:

       uses: taiki-e/install-action@cross

[notgull]

Hmm, looks like the new version broke the other targets. Not sure if there's a way around this.

[taiki-e]

I think rustup target add+cargo build --target would work for targets that cross does not support. (This crate is a library and does not require a linker or libraries to build the library part.)

polling/.github/workflows/ci.yml

Lines 100 to 101 in e10c7e8

	rustup target add x86_64-unknown-illumos
	cargo build --target x86_64-unknown-illumos

Looks like the FreeBSD/NetBSD builds are failing here... actually, can we just remove them, since we're testing them anyways using Cirrus/vmactions?

[taiki-e]

Yeah, there is no need to build NetBSD and FreeBSD by using cross as they have been tested elsewhere.

It may be a good idea to leave a comment on cross job about we are testing BSDs using Cirrus/vmactions.

Also you may need to change the target triple for Fuchsia from x86_64-fuchsia to x86_64-unknown-fuchsia.

https://github.com/rust-lang/rust/blob/master/RELEASES.md#version-1680-2023-03-09

Add vendor to Fuchsia's target triple

Thanks!
