[GTK] Mesa build fails over llvm-3.5

[ChangSeok Oh]

I saw a build break for Mesa while running update-weebkitgtk-libs on Ubuntu 14.10.

  CXX      gallivm/lp_bld_debug.lo

After investiongation on this, I found a relevant fix from mesa upstream. http://cgit.freedesktop.org/mesa/mesa/commit/src/gallium/auxiliary/gallivm/lp_bld_debug.cpp?id=564821c917f4a9d5a0de2ee77b90b0cd85e3d3a6
I believe we need it.
