changes to prepare for that.

(cherry picked from commit 64cdd4b714)
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
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.
Avoid issues with non-native builds by splitting up the packages a
little closer to how they should be while still leaving the main package
containing everything Rust uses. This makes it possible to build
rust-llvm for the target, hopefully improving issue #81.
Future versions of LLVM require cmake to build so it will be easier to
prove that out on a known good build and to allow future versions to use
this as common code.
Convert rust-llvm to not use the shared source setup and instead use its
own extracted directory. Include the version info in the bitbake file so
that in the future we can support multiple versions via a
PREFERRED_VERSIONS variable.
