[Pkg-opencl-devel] Bug#972620: dwarf-column-info patch

[Drake Diedrich]

I've had this for a while too and been looking. Not all versions of clang
have -dwarf-column-info, and the clang version just changed.  What worked
for me was just deleting it from intel-opencl-clang.
intel-grahics-compiler validates the flag and passes the errors back up,
but isn't where the flag is added to the compiler options.  Changing
intel-opencl-clang allowed compiles again.  I don't know what the
consequences are for debugging and profiling (since I haven't used those),
but not compiling is worse.
