supported since the 12th release, while 11.4 is EOL since 2021.

CMAKE_SYSTEM_NAME is defined on a cross build if the target is
recognized.  Without this explicit definition cmake will assume that
we're building for the host platform which can bring in unwanted
compiler and linker flags.

Also, add a warning on cross builds with unknown target to aid in
cross builds for future platforms.

Now that we have fixed the underlying cause of long type name
inconsistencies in rust-lang#113893, we can remove the remap-path-prefix logic
from CI

Squelch a noisy rustc_expand unittest

The test `rustc_parse::tests::bad_path_expr_1` prints an error message to stderr, circumventing libtest's stderr intercept. This causes noise when running tests, in particular they show up 16 times on the GitHub Actions summary page. The solution here is to not use an error emitter that prints to stderr, and instead check that the correct error is generated.

Define CMAKE_SYSTEM_NAME on a cross build targeting DragonFly.

Without `CMAKE_SYSTEM_NAME` set to the target  a cross compile will generally fail.  Related to rust-lang#109170.

Add `sym::iter_mut` + `sym::as_mut_ptr` for Clippy

We currently have `sym::iter` and `sym::iter_repeat`, this PR adds `sym::iter_mut` as it's useful for rust-lang/rust-clippy#11038 and another Clippy lint, it also adds `sym::as_mut_ptr` as it's useful for rust-lang/rust-clippy#10962.

Remove -Z diagnostic-width

This removes the `-Z diagnostic-width` option since it is ignored and does nothing. `-Z diagnostic-width` was stabilized as `--diagnostic-width` in rust-lang#95635. It is not entirely clear why the `-Z` flag was kept, but in part its final use was removed in rust-lang#102216, but the `-Z` flag itself was not removed.
