595d5b2faf test: Fix a spuriously failing test on valgrind 
It's unclear to me whether this test failing under valgrind is actually legit.
The test only fails in valgrind when everything is dynamically linked, and it
appears to work when statically linked.

For now just add the `// no-prefer-dynamic` directive and let's just chalk it up
to a weird valgrind issue.

Closes #31328

463e42701a Auto merge of #31735 - aliclark:freebsd-link-defs, r=alexcrichton 
The FreeBSD linker config is missing some options present in the other BSD configs.

This seems accidental, with other BSDs having the flags added in platform-specific commits, or with the flags present from day 1.

Some other BSD commits for reference:

8842e28be8 Auto merge of #31684 - tmiasko:alternate-stack, r=alexcrichton 
Remove alternate stack with sigaltstack before unmaping it.

Also reuse existing signal stack if already set, this is especially
useful when working with sanitizers that configure alternate stack
themselves.

This change depends on SS_DISABLE recently introduced in libc crate and updates
this git submodule accordingly.

6b076c2daa Auto merge of #31734 - aliclark:bsd-stat-fixes, r=alexcrichton 
In https://github.com/rust-lang/rust/issues/25155 the os::freebsd::raw stat was split for the x86 vs. x86-64 cases, which appears to have been done to implement the padding on the end of struct stat for the x86 case (the struct is otherwise the same notwistanding the size of long).

This PR de-duplicates the struct using #[cfg(target_arch = "x86")] for the __unused field, which also fixes the definitions which had sinced changed with the LFS work d088b67187.

Also changed definitions to c_long for dragonfly and freebsd where appropriate.

Also removes some unused imports that the compiler was complaining about.

7dd3b20119 Auto merge of #31727 - semarie:openbsd-llvm-cpu, r=alexcrichton 
The initial purpose is to workaround the LLVM bug
https://llvm.org/bugs/show_bug.cgi?id=26554 for OpenBSD.

By default, the `cpu` is defined to `generic`. But with a 64bit
processor, the optimization for `generic` will use invalid asm code as
NOP (the generated code for NOP isn't a NOP).

According to #20777, "x86-64" is the right thing to do for x86_64
builds.

Closes: #31363

96c8a67a17 Rollup merge of #31695 - oconnor663:chardocs, r=alexcrichton 
Previously the docs suggested that '❤️' doesn't fit in a char because
it's 6 bytes. But that's misleading. 'a̚' also doesn't fit in a char,
even though it's only 3 bytes. The important thing is the number of code
points, not the number of bytes. Clarify the primitive char docs around
this.
