Pull request description:

  This switches us to using a [LLD](https://lld.llvm.org/) based toolchain for macOS builds.

  ### Benefits
  * Less complicated macOS toolchain.
  * No longer beholden to Apple releasing it's [source](https://opensource.apple.com/source/) for [cctools](https://opensource.apple.com/source/cctools/), [ld64](https://opensource.apple.com/source/ld64/) & [libtapi](https://opensource.apple.com/source/tapi/).
  * No more reliance on third parties to modify those sources for us. i.e [apple-libtapi](https://github.com/tpoechtrager/apple-libtapi), [cctools-port](https://github.com/tpoechtrager/cctools-port) (cctools + ld64).

## Deterministic macOS App Notes
macOS Applications are created in Linux by combining a recent `clang` and the Apple
`binutils` (`ld`, `ar`, etc).
macOS Applications are created in Linux using a recent LLVM.
Apple uses `clang` extensively for development and has upstreamed the necessary
functionality so that a vanilla clang can take advantage. It supports the use of `-F`,
`-target`, `-mmacosx-version-min`, and `-isysroot`, which are all necessary when
building for macOS.
Apple's version of `binutils` (called `cctools`) contains lots of functionality missing in the
FSF's `binutils`. In addition to extra linker options for frameworks and sysroots, several
other tools are needed as well. These do not build under Linux, so they have been patched to
do so. The work here was used as a starting point: [mingwandroid/toolchain4](https://github.com/mingwandroid/toolchain4).
In order to build a working toolchain, the following source packages are needed from
Apple: `cctools`, `dyld`, and `ld64`.
These tools inject timestamps by default, which produce non-deterministic binaries. The
`ZERO_AR_DATE` environment variable is used to disable that.
This version of `cctools` has been patched to use the current version of `clang`'s headers
and its `libLTO.so` rather than those from `llvmgcc`, as it was originally done in `toolchain4`.
To complicate things further, all builds must target an Apple SDK. These SDKs are free to
download, but not redistributable. See the SDK Extraction notes above for how to obtain it.
