With std_detect being able to put a runtime check for FreeBSD, Windows,
and macOS, "... are only supported on linux-based platforms" is inaccurate.

Also, what "support" means was confusing: it was unclear whether it was
talking about the result of the runtime check, or whether the macro
could provide a runtime check at all.

I don't think it's useful to talk about the result of the runtime
detection because the main point of this macro is to determine the
result at runtime.

Amend to talk about the fallback behavior for miss runtime implementation.

Alternative sugguestion would be to delete the whole paragraph.
