rust: strip whitespace from features

This whitespace in here causes rust to not be happy with the features
and throw warnings about a feature such as ' +sse3' being unsupported
when '+sse3' works just fine. Amazingly will cause rustc to abort when
you try to resolve the features to valid configs with the `--print` arg
to rustc.

 ## What works:
 
- - Building `rust-native` and `cargo-native`
- - Building Rust based projects with Cargo for the TARGET
-   - e.g. `rustfmt` which is used by the CI system
- - `-buildsdk` and `-crosssdk` packages
+ - MACHINE="beaglebone" (TARGET_SYS=arm-poky-linux-gnueabi)
+ - Building rust-native, rust-cross, rust-hello-world, cargo-native
+ - Running/using all of these (including rust-hello-world)
 
 ## What doesn't:
 
- - Using anything but x86_64 as the build environment
- - rust (built for target) issue #81
+ - Probably some of the untested things
 
 ## What's untested:
 
- - cargo (built for target)
+ - rust (built for target)
+ - Other TARGETs
 
-## Building a rust package
+## Common issues when packaging things using cargo
 
-When building a rust package in bitbake, it's usually easiest to build with
-cargo using cargo.bbclass.  If the package already has a Cargo.toml file (most
-rust packages do), then it's especially easy.  Otherwise you should probably
-get the code building in cargo first.
+ You may run into errors similar to:
 
-Once your package builds in cargo, you can use
-[cargo-bitbake](https://github.com/cardoe/cargo-bitbake) to generate a bitbake
-recipe for it.  This allows bitbake to fetch all the necessary dependent
-crates, as well as a pegged version of the crates.io index, to ensure maximum
-reproducibility.
+```
+| src/lib.rs:12:1: 12:35 error: can't find crate for `ffi`
+| src/lib.rs:12 extern crate "openssl-sys" as ffi;
+|               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+```
 
-NOTE: You will have to edit the generated recipe based on the comments
-contained within it
+ Where a "-sys" crate (or other crate) is not found. These are typically caused
+by a crate's Cargo.toml including triplet-specific dependencies and then using
+the crate based on a feature (most often, `#[cfg(unix)]`). Until cargo and it's
+ecosystem get their act together, you'll need to supply patches to the
+misbehaving packages. See `recipies/cargo/cargo_*.bb` for an example of how to
+do this.
 
 ## TODO
 
+ - -crosssdk and -buildsdk packages
+ - Upstream local rustc patches for libdir and bindir support
+ - add bitbake fetch support for crates.io
+ - add required cargo package registry clones in SRC_URI to prevent the need
+   for network when building.
+
 ## Pitfalls
 
- - TARGET_SYS _must_ be different from BUILD_SYS. This is due to the way Rust configuration options are tracked for different targets. This is the reason we use the Yocto triples instead of the native Rust triples. See rust-lang/cargo#3349.
+ - TARGET_SYS _must_ be different from BUILD_SYS. This is due to the way configuration options are tracked for different targets.
 
 ## Dependencies
 
 On the host:
- - Any `-sys` packages your project might need must have RDEPENDs for
- the native library.
+	unknown
 
 On the target:
- - Any `-sys` packages your project might need must have RDEPENDs for
- the native library.

 The master branch supports the latest master of poky. When poky creates releases, we will create a branch with the same name as the poky release. This release branch should always work with that poky release. Note that these release branches will typically be less tested than the master branch.

-# So when building '-native' packages BUILD_SYS == HOST_SYS == TARGET_SYS

-# - TARGET - the system where the binary will run

-# - triple suffix (e.g. CC_x86_64_unknown_linux_gnu) - both
-#   see: https://github.com/alexcrichton/gcc-rs

-http2 requires that curl is build with nghttp2 which in turn depends on

+Setting HLIB specially for stage0 (and even more specially for windows)

+the place requested by configure, use '-L' and '--sysroot' to point
+stage0-rustc at the appropriate location.

+Subject: [PATCH 5/9] configure: support --bindir, and extend libdir to
+ non-blessed dirs
+
+Adds --bindir, and:
+
+Allows --bindir and --libdir to have multiple elements in their paths
+relative to sysroot, and allows libdir to end in an arbitrary directory
+(previously it was limited to lib, lib32, and lib64).
+
+Note that this assumes absolute paths start with '/', which may break
+windows platforms

+Subject: [PATCH 10/12] rustc_trans: make .note.rustc look more like debug info
+
+Mark the global variable as const and private so the resulting section
+is not flagged as writable and to avoid putting an unnecessary symbol in
+the dynamic table of shared objects.
+
+Unfortunately there doesn't seem to be a way to avoid the section being
+marked SHF_ALLOC when declared as a variable in LLVM. Hack around that
+by using objcopy to clear the flags on the section before the final
+link.
+
+This places the section at the end of the executable so it can be
+stripped later without rearranging important code/data sections.

+Subject: [PATCH 11/12] Allow overriding crate_hash with -C crate_hash
+
+The current crate hash is not stable from run-to-run.  This causes
+problems with bitbake; it needs a guarantee that every build with the
+same input will generate compatible output, otherwise sstate won't work.
+Using -C crate_hash, we can do that by using the bitbake input hash to
+determine the crate hash; the bitbake input hash will be stable, but
+still different for different rust recipes.
