As discussed in [1], some changes to dead code warnings caused a lot of

check.

hurd: Fix build from missing `fpos_t`

In 872642ad ("gnu: Add proper structs for fpos_t and fpos64_t"),
`fpos_t` was changed from an opaque struct to one with a definition on
Linux GNU, with the Unix fallback configured as for targets without a
GNU `target_env`. However, GNU hurd matches `target_env = "gnu"`, but
doesn't have a `fpos` implementation.

Fix the build by adjusting the fallback `cfg` to be more specific.
Eventually we probably want the same definition on Hurd as on Linux.

Replace handwritten `Debug` impls with derives

`s_no_extra_traits!` doesn't derive `Debug` so there are a lot of
handwritten implementations. However, since we have a derive-like
solution for unions now (printing them like an opaque struct), there
really isn't any reason these can't all be derived.

Add `derive(Debug)` to `s_no_extra_traits`, still gated behind `feature
= "extra_traits"`, which allows getting rid of manual implementations.

gnu: Update struct timespec for GNU _TIME_BITS=64

Use a GNU libc specific version of struct timespec in
unix/linux_like/linux/gnu and keep the version in unix for all other
unix libc's.

Big-endian platforms wants 32 bits of padding before tv_nsec,
little-endian after.

GNU libc always uses long for tv_nsec.

Add arc4random and arc4random_buf to NuttX

Add arc4random and arc4random_buf to NuttX

* Declare `arc4random` and `arc4random_buf` as extern "C" functions in the NuttX module
* Enable access to system-provided random number generation for NuttX targets
* Aligns NuttX FFI with other Unix platforms that expose these functions

This change allows Rust code targeting NuttX to use `arc4random` and `arc4random_buf` for secure random number generation, improving compatibility and feature parity with other targets.
