>Does fil-clang have `-fno-` flag to control disabling fil-c stuff?
No. I could add a flag like that, but that would make my patch to clang larger, which would make rebasing to new clang versions harder.
So I'm choosing not to add such a flag. For now.

I support both glibc and musl.
LFS is glibc-based.
If you do get around to adding the flag, consider a suggestion for the color of bikeshed: `-fyolo`. (Can't find my April Fool's clang patch for adding `-feverything`; hard to search the phab archive)
