If we use the default of None, we get a python exception in
find_and_diagnose_missing() instead of printing a sensible error message.

We always want to build the table of contents. Additionally, we also
set the flag to make the output deterministic which is already the
default for llvm-ar.

Popen.communicate() method in Python 2 returns a pair of strings, and in
Python 3 it returns a pair of byte-like objects unless universal_newlines
is set to True. This led to an error when using Python 3. With this patch,
merge_archives.py works fine with Python 3.
Thanks to Sergej Jaskiewicz for the patch.

ar doesn't produce the correct results when used for linking static
archives on Apple platforms, so instead use libtool -static which is
the official way to build static archives on those platforms.

Summary:
I can't see a good reason to disallow this, even though it isn't the
standard way we build libc++ for Apple platforms.
Making this work on Apple platforms requires using different flags for
--whole-archive and removing the -D flag when running `ar` to merge
archives because that flag isn't supported by the `ar` shipped on Apple
platforms. This shouldn't be an issue since the -D option appears to be
enabled by default in GNU `ar`.

glob can return files in arbitrary order which breaks deterministic
builds. Rather, use `ar t` to list the files in each archive and
preserve the original order. Using `ar q` results in duplicate entries
in the archive, instead use `ar r` to avoid duplicates.

to reflect the new license. These used slightly different spellings that
defeated my regular expressions.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Using the system default 'ar' might not be the right choice when
cross compiling.
Don't prepend the ar options by a dash, not all ar implementations
support that (llvm-ar doesn't).
Also pass the 's' option when creating the merged library, to create
an index.
