[PATCH] D21968: [libcxx] Externally threaded libc++ variant - Take 2

[Eric Fiselier via cfe-commits]

EricWF added a comment.

This looks great.  Two comments:

1. The declarations should be used in both the inline and external pthread implementation. They also need visibility declarations.
2. Why can't we use the inline implementation to implement `external_threads.cpp`?

I took a stab at it here <https://gist.github.com/EricWF/0edfd18c22cd50a5f34fd11674f4eda9>.

After that this LGTM.

----------------
When this is building as a shared library it needs to do the `-nodefaultlibs` dance to prevent linking to libstdc++.so or other unwanted system libraries.
