[Beignet] [PATCH 1/3] add option BUILD_STATIC_GBE_COMPILER to build static compiler

[Guo, Yejun]

Just build libcl.so and libgbeinterp.so in the old c/c++ environment, and use the offline compiler that built in mainstream c/c++ environment. It will make beignet workable with CL_EMBEDDED_PROFILE in the old c/c++ environment, please refer to my next two patches of this patch set.

Do you have plan to support to build libcl and libgbe_interp in static way? Only add static in CMakeList.txt will not work, because init function will not be called if we use libcl.a and libgbe_interp.a, but it works for libcl.so and libgbe_interp.so.
