@openal-soft: fix build on SunOS

@$NetBSD$

Kludge for Illumos: C11 <threads.h> is not supposed[1] to be used from C++11
mode and it causes the C11 macro to be defined for thread_local.
Undefine this, thread_local is a compiler builtin in C++11.
We can't drop the include since that causes other issues.
