[Beignet] Another build failure with current master

[Yichao Yu]

Hi,

I've got an error when generating src/kernels/cl_internal_*_str.c's.

The error message reads

error: OpenCL version was  in PCH file but is currently ������zzzz{{{{
build the file /home/yuyichao/projects/mlinux/pkg/all/beignet-git/src/beignet/src/kernels//cl_internal_built_in_kernel.cl
failed

Note the non-ascii (non-utf8) characters even when I set locale to C.

The command line executed was

Doesn't work with either CLANG or GCC (probably unrelated). llvm version 3.5.0.
