Or use libtls.la instead of libtls.a. Unfortunately that doesn't work
because their test cases use some internal symbols of their libraries,
which are not exported in the shared libraries. By linking directly to
the static variant, there is no symbol visibility mechanism, and
therefore they can access all symbols.

So, indeed, it's not that easy, and using the CMake build system makes
sense.

So: applied to master. Thanks!
