Subject: [boost] [asio][android][clang-x86] cannot locate symbol "___tls_get_addr"

As you can see at, there
are many fails on Android/x86, when tests are built by clang.

There was ticket filed to CrystaX NDK tracker about that: After some research, I've found
reason of fails and created pull request for Boost.Asio: Shortly speaking, there is
intersection of several bugs - one is inability of clang to emulate
thread-local variables without support from underlying runtime (gcc can
do that), and second is misconfiguration in Boost.Asio headers.

I've tested locally with change from and all '___tls_get_addr'
errors disappeared. Now I'm waiting for that pull request to be merged
into upstream, but I don't see any activity in Boost.Asio repository. Is
there something wrong with my pull request? It's very simple so I wonder
why it not yet merged?

I'd like to see it merged to the upstream (including 'master') before
1.58 release - just because this bug cause not only Boost.Asio fails,
but several others libraries too.
