Provide builds for linux

[K1ll3rF0x]

Hi,

I am working closely with WebCL related stuff by utilising Nokia's WebCL plugin. However, I do not have a proper access to Windows 8 to test your WebCL implementation.
Could you provide a linux build (e.g. 32 and 64 bit Ubuntu/Debian first) in the near future so your implementation can be tested on linux platforms.

We would gladly accept pull request for linux build.
