ARM_INSTRUCTION_SET, and therefore ARM_THUMB_OPT also, expect to only be
used in conjunction with the thumb TUNE_FEATURES. So thumb-mode should only
be added if thumb is in TUNE_FEATURES and ARM_THUMB_OPT is thumb.
The commit https://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/meta/conf/machine/include/arm/arch-armv7a.inc?id=3e7d26e31a724009e69788460737e07163a14051
caused armv7a.inc to set ARM_INSTRUCTION_SET to thumb and the commit
message explicitly states that the change should have no effect unless
TUNE_FEATURES also includes thumb. This change to rust will allow that
assumption to continue to be true.
musl builds need libunwind.a to be in sysroot for libstd-rs to build
unwinding support into it. This also means we need to compile libunwind
with --enable-static in oe-core

We were already trying to disable assertions, but it wasn't working.
rust-llvm now configures assertions based on the CMAKE_BUILD_TYPE.
Setting that to "Release" causes assertions to be disabled, which is
what we want.
Further changes needed for musl to work.
env needs to be set to "musl" for unwinding work properly.
Also the llvm target should end with "-musl" and not "-gnu".
Put rust-llvm into a directory of it's own. This avoids conflicts
between the official llvm and rusts temporary one. It solves
interoperability issues with meta-clang.
Use /usr/lib/llvm-rust/ as prefix because that matches what llvm does
themselves on debian and ubuntu.
When yocto is searching for lib dependencies it uses SONAMES and RPATHS to find
the right one. When we compile a rust package which dynamically links to rust's
libstd, yocto will not be able to find the matching dependency in shlib and
will complain with a warning. Even worse, if you have compiled go-runtime, the
build will find go-runtime as provider of libstd and will complain that you
missed a RDEPENDS to go-runtime - this is completely wrong obviously.
This patch adds SONAME to rust's stdlib. In this way yocto will create the
required provider and packages dynamically linking to it will be able to find
libstd-rs as a provider of stdlib.

Support for mips32 big (mips) and little endian (mipsel) for mips32
and mips32r2 cpus. The big endian target can be verified with the
qemumips machine.
The "target_c_int_width field is added to librustc_back since rust
1.22.0 because not all rust targets (e.g. msp430-none-elf, avr)
have 32-bit int types any more.
Switch the build process to using Rust's new build system called
rustbuild. At the same time stop using jemalloc on all platforms and
switch to the system allocator since that was simplier to do.
We'll need the prior version of cargo to boot strap ourselves going
forward so include the version info so we can support multiple versions
in the tree.
Generate the Cargo recipe with cargo-bitbake instead of having a
handcrafted recipe. This should make future version bumps easier.
Three known issues:
- license checksum of the Apache license is a generateme value
due to the license file having a difference name then what's in
Cargo.toml.
- branch= value was wrong for tags. Pointed to HEAD instead of the
branch that the underlying tag commit came from.
- Use https protocol when the repo is publicly accessible.
Technically these dependencies change between versions. It just happens
that these two versions didn't change the dependencies but future
versions will so preemptively make the adjustment.
The path to the rust source changes from 1.15 so preemptively make
changes to prepare for that.
