bors b17d4e335d auto merge of #10299 : alexcrichton/rust/osx-loader-path-fix, r=brson
According to apple's documentation of rpath semantics, `@executable_path` means
that the path is relative the the *process executable*, not necessarily the
library in question. On the other hand, `@loader_path` is the path that points to
the library which contains the `@loader_path` reference. All of our rpath usage is
based off the library or executable, not just the executable. This means that on
OSX we should be using `@loader_path` instead of `@executable_path` to achieve the
same semantics as linux's $ORIGIN.

The purpose of this is to unblock the current snapshot from landing. It appears that because we were propagating linker arguments we never saw this before. Now that we're no longer printing linker arguments, we're depending on the libraries to resolve their own references. In using `@executable_path` on OSX, libraries in different locations than the executable were not able to resolve their references (because their rpaths listed were all relative to the location of the library, not the executable).

I'm still a little unclear on how this ever passed locally on my own machine, but it's clear why this is failing on the bots at least.

This is a preliminary version of the Rust compiler, libraries and tools

Source layout:

librustc/          The self-hosted compiler

libstd/            The standard library (imported and linked by default)
libextra/          The "extras" library (slightly more peripheral code)
libsyntax/         The Rust parser and pretty-printer

rt/                The runtime system
rt/rust_*.cpp      - The majority of the runtime services
rt/isaac           - The PRNG used for pseudo-random choices in the runtime
rt/bigint          - The bigint library used for the 'big' type
rt/uthash          - Small hashtable-and-list library for C, used in runtime
rt/sync            - Concurrency utils
rt/util            - Small utility classes for the runtime.
rt/vg              - Valgrind headers
rt/msvc            - MSVC support

test/              Testsuite
test/compile-fail  - Tests that should fail to compile
test/run-fail      - Tests that should compile, run and fail
test/run-pass      - Tests that should compile, run and succeed
test/bench         - Benchmarks and miscellanea
test/pretty        - Pretty-printer tests
test/auxiliary     - Dependencies of tests

compiletest/       The test runner

librustpkg/        The package manager and build system

librustdoc/        The Rust API documentation tool

llvm/              The LLVM submodule

libuv/             The libuv submodule

rustllvm/          LLVM support code

libfuzzer/         A collection of fuzz testers

etc/               Scripts, editor support, misc
