From the PR headmatter:

But now it fails in php

This giant callstack makes me believe this PR isn't suitable for merging yet. I'd like to merge something that fixes an entire problem, rather than moving the symptom from one location to another.

This appears to be a __structuredAttrs-related issue. Is that right?

It also undoes the last change to the helper by @Artturin in #225929. Let's direct our attention to making the location of NIX_CFLAGS_COMPILE canonical throughout nixpkgs, or having a more compelling reason for the code in this PR other than a symptom shifting from one location to another.

[philiptaron]

This was introduced in #135533 and last modified in #225929.

[philiptaron]

See also the closed PR #393458 which attempted much the same thing.
