We have stable options for adding linker arguments; we should have a stable option to help debug linker arguments.
The documentation makes it clear that the *exact* format of the output is not a stable guarantee.

- [bootstrap: tidy up flag handling for llvm build][93918]
Compatibility Notes
-------------------
- [Remove compiler-rt linking hack on Android][83822]
- [Mitigations for platforms with non-monotonic clocks have been removed from
`Instant::now`][89926]. On platforms that don't provide monotonic clocks, an
instant is not guaranteed to be greater than an earlier instant anymore.
- [`Instant::{duration_since, elapsed, sub}` do not panic anymore on underflow,
saturating to `0` instead][89926]. In the real world the panic happened mostly
on platforms with buggy monotonic clock implementations rather than catching
programming errors like reversing the start and end times. Such programming
errors will now results in `0` rather than a panic.
- In a future release we're planning to increase the baseline requirements for
the Linux kernel to version 3.2, and for glibc to version 2.17. We'd love
your feedback in [PR #95026][95026].
