Add workaround for when clang is used as a compiler, due to a tail calls
optimization bug in llvm when PIC mode is used. This bug was reproduced with
3.2 and 3.1 on i386. And prevents modules that where dlopen()'d by the
xorg-server, to dlopen() other shared modules by themself.
This is known to happen with the vmware and vesa drivers others might be
affected.
