The oe-core/poky change 'base.bbclass wipe ${S} before unpacking
source' (poky: a56fb90dc3805494eeaf04c60538425e8d52efc5, oe-core:
eccae514b71394ffaed8fc45dea7942152a334a1) wipes ${S} in do_unpack prior
to unpacking. This breaks our shared source as we set ${S} to the shared
location, and don't actually unpack anything (the result is we try to
build rustc without any source code, which fails predictably)
Avoid this by clearing do_unpack[cleandirs].
At the same time take pieces of gcc-shared-source.inc and note how & why
we differ from how gcc operates.
This is a bit of a hack, and only happens to work because we know the
exact method that do_unpack uses to clear ${S}, and using python()
happens to get called at the "right time".
RUSTFLAGS is used by Cargo and always passed to the compiler. Put our
non-standard crate_hash argument there because it is required for
reproducible builds.
Add the rpath option to avoid having to patch Cargo.toml for this and
remove the function that does so.

rust-bin.bbclass now only contains what is necessary to build crates
using the rust compiler directly and rust.bbclass contains information
shared between rust-bin and cargo.

If this dependency is missing its possible that openssl won't be built
before libgit2 is built and then we won't have git support over SSL
which leaves out a lot of git repos.
The August snapshot is no longer new enough for rust 1.7.0. Without the
update rust's build process still tries to download its own snapshot,
which rather defeats the point of this.
Rust 1.7.0 uses a snapshot from 2015-12-18 and not 2015-08-11. Without
this change Rust will fetch the snapshot during the build process which
will fail on Yocto builds that disable network outside of the fetch
phase.

The existing feature parsing is specific to ARM so we need to add
support for x86. This is a little more generic since the variable we
parse is changed if we're building for the host, cross or actual target.

This generates an appropriate CPU value for the targets. For ARM it
leaves the default of 'generic' since we build up all the different CPU
differences in the 'features' field but for x86/x86_64 we need to pass
an appropriate CPU value.

The code previously wrote out a JSON file but used basic string handling
instead of the Python JSON library. Its cleaner to use the Python JSON
library.
