Andrey Semashev dea6b04157 Added workarounds for gcc < 4.7 on Linux and OpenBSD. ...

Apparently, gcc < 4.7 on Linux also don't have __cxa_get_globals
declaration in cxxabi.h. Declare the function ourselves.

Also, on OpenBSD it seems there is no declaration either, and
on that platform the function implementation has no exception
specification, like on FreeBSD. Add a declaration of that platform.

Lastly, changed __cxa_get_globals and _getptd-based implementations
to avoid violating strict aliasing rules. This is still formally UB
to access structure fields like we do, but this is one less reason to
cause miscompilation or compiler warnings.
