When a rustc cfg is defined both with and without value, the environment variable should provide all the values. Before this change, it ended up being empty.

Fixes: #11789

Can a test be added for this (maybe in build_script_env.rs)?

@arlosi Can you say why you nominated this for beta? My understanding is that target_has_atomic without a value only exists on nightly.

Can you say why you nominated this for beta

I think we just did the 1.69 beta fork, so wouldn't the bug be present there (since this didn't make it)?

edit: I misread it, yes it's nightly only, so:

~~This update is primarily for making rust-lang/cargo#11630 into 1.69~~ (will file a beta backport then). However, just look into the licenses and dependencies permitted list, it looks a bit unfortunate but inevitable I guess?
