The way LLVM builds its native utilities is not safe (it runs a
recursive cmake in the same work directory as the main instance). To
prevent those instances from stepping on each other, we'll build the two
native utilities separately before starting the main build.
Fixes issue #143
This is a fast case if the slave has a local checkout available so that
it doesn't have to do a full clone. The check unfortunately didn't take
into account all cases and failed on the new slave.
This patches handle changing the directories that things are installed
in but appear to be unused. They were likely used before rust-cross was
split out to not install files.

Not sure what version this patch appears to have become unnecessary but
I verified it by checking the output in
build/tmp/sstate-control/manifest-x86_64-rust-native.populate_sysroot
and the installed files and their paths didn't change with and without
this patch.

compiler-rt-dev and compiler-rt-staticdev.

(cherry picked from commit fcbebdf58f)
The -C crate_hash option does not work if multiple versions of the same
crate are being linked into a binary. This can happen if different
dependencies depend on different versions of the same crate. The -C
crate_hash argument causes all versions of a given crate to have the
same crate hash which in turn causes the compiler to select the wrong
one internally and crash. This works around issue #126 for Cargo builds
but does not fix the underlying cause.
Reworked the source redirection to use directory source redirection like
I've done for Gentoo. This allows us to specify all crate dependencies
in the bitbake SRC_URI and have Yocto fetch them down using our crate
fetcher and then Cargo will build without reaching out to the network.
Redid how compiler-rt is built by using the Rust makefiles to build it
instead of compiler-rt's build system. Rust itself deviated from using
compiler-rt's build system and provided their own rules requiring the
source tree to be configured to use them.
We need the Rust snapshot (stage0) for the build environment not the
host environment. This is not affecting us currently because we are only
building native versions of this today but should improve the behavior
of #81 or if any Rust components are built for the target machine.
Since we no longer use shared source we can modify the source directory
as we build. This drops another patch we need to build and simplifies
the addition of Rust 1.12.1 in #97.
Don't supply the linker arguments via rustflags and then mangle with the
RUSTFLAGS environment variable. This is also a parial reversion of
4e1bda643e and 5afc0cc471. These changes are reverted since it assumed
people would build with cargo and not directly with rustc. ref #116.
We don't use the native Rust triples but instead use the Yocto triples
so we need to provide this override properly. This typo was introduced
in 5afc0cc471.
