Subject: [boost] [testing] Add a tester with hidden visibility

Is it possible to add a tester that enables hidden visibility (-
fvisibility=hidden -fvisibility-inlines-hidden) when building and testing
Boost? I believe, a single tester on Linux+GCC would be enough to discover
most issues related to symbol visibility.

The reason I'm asking is that I believe Boost should support building with
hidden visibility by default. This mode allows more optimizations and does not
export unintended symbols from libraries.

I've set hidden visibility for Boost.Log (in develop) and, as I understand,
Robert is doing a similar change in Boost.Serialization. However, when
building 1.58 with hidden visibility for my project I found out that not all
libraries work well with that setting.

What do you think about it?
