gegl don't askfor cl/gl extensions
The tests/compositions/clones.xml from gegl test suite segfaults when using
mesa OpenCL on Radeon HD 7570 (AMD Turks). I tired running it in gdb, here's
the backtrace:
[New Thread 0x7fffca312700 (LWP 8187)]
Program received signal SIGSEGV, Segmentation fault.
0x00007fffffffc8b0 in ?? ()
(gdb) bt

namespace)::InlineSpiller::insertSpill(unsigned int, bool,
llvm::MachineBasicBlock::bundle_iterator<llvm::MachineInstr,
llvm::ilist_iterator<llvm::MachineInstr> >) ()
from /home/vesely/.local/lib/libLLVMCodeGen.so
Backtrace stopped: previous frame inner to this frame (corrupt stack?)
llvm, clang, mesa, libclc, gegl, babl are all latest git as of today.
Note that I had to patch gegl in order to use OpenCL on mesa at all (it
requires some GL/CL extensions). The patch is attached.
Note that the same test crashes when using intel-ocl too.
