Note that setting RUSTFLAGS as an environment variable does not merge with rustflags from config tomls, which is why I thought this would be cleaner. It seems there is no workaround to set these always when a nightly compiler is used now :/ Ref: rust-lang/cargo#14733

Any way, the only other place that is currently using rustflags I suppose is

yew/.cargo/config.toml

Lines 7 to 8 in fb2046c

	[target.wasm32-unknown-unknown]
	rustflags = ['--cfg', 'getrandom_backend="wasm_js"']

which is for an example only which doesn't need to use nightly_yew, so we are fine!

[Madoshakalaka]

I was wondering if this PR actually changed the actual flags passed and would cause problems.

Thanks for the confirmation!
