Some other shufflings as well:
* Three powerpc triples for Linux have been added recently
* An armv7 linux triple was added recently
* The 64-bit Solaris triple is now mentioned in tier 3
We are currently now also building nightlies for iOS, powerpc triples, and
armv7, but there hasn't been much vetting of the triples themselves so I've left
them in tier 3 for now.
This PR refactors away `Module`'s `external_module_children` and instead puts `extern crate` declarations in `children` like other items, simplifying duplicate checking and name resolution.
This PR also allows values to share a name with extern crates, which are only defined in the type namespace. Other than that, it is a pure refactoring.

Currently any compilation to MIPS spits out the warning:
'generic' is not a recognized processor for this target (ignoring processor)
Doesn't make for a great user experience! We don't encounter this in the normal
bootstrap because the cpu/feature set are set by the makefiles. Instead let's
just propagate these to the defaults for the entire target all the time (still
overridable from the command line) and prevent warnings from being emitted by
default.
This reverts PR #30324, fixing bug #30159 in which a public a glob import makes public any preceding imports that share a name with an item in the module being glob imported from.
For example,
```rust
pub fn f() {}
pub mod foo {
fn f() {}
}
mod bar {
use f;
use f as g;
pub use foo::*; // This makes the first import public but does not affect the second import.
}
```
This is a [breaking-change].
The target was meant as a modern generic `armv7` option, therefore a few changes were necessary:
- gcc's `-march=armv7` was causing compilation failures on modern linux systems
- rust codegen defaulted to `cortex-a7` causing illegal instruction crashes on previous `armv7-a` processors (e.g, cortex-a5, cortex-a8)
There is no `Drop` implemented for `Child`, so if it goes out
of scope in Rust-land and gets deallocated, the child process
will continue to exist and execute. If users want a guarantee
that the process has finished running and exited they must
manually use `kill`, `wait`, or `wait_with_output`.
Fixes#31289.
This target covers MIPS devices that run the trunk version of OpenWRT.
The x86_64-unknown-linux-musl target always links statically to C libraries. For
the mips(el)-unknown-linux-musl target, we opt for dynamic linking (like most of
other targets do) to keep binary size down.
As for the C compiler flags used in the build system, we use the same flags used
for the mips(el)-unknown-linux-gnu target.
