[Mesa-dev] removal of _glthread_GetID() breaks libglapi.so's ABI

[Chia-I Wu]

Hi Brian,

_glthread_GetID() was removed by this commit

    mesa: remove remaining uses of _glthread_GetID()

It turns out the function, declared in glapi.h, is a part of
libglapi.so ABI.  I am now getting this error when building GL
applications

/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/libGL.so:
undefined reference to `_glthread_GetID'

(gcc finds distro-provided libGL.so, which finds my build of
libglapi.so because of LD_LIBRARY_PATH).

I wonder if we should give the symbol available.  It could simply return zero...
