[Openmp-dev] Removing extra files copy

[C Bergström]

Hi

When importing openmp cmake and doing a parallel multi-target
(32/64bit) build - there is a race condition when copying some files.

When looking into this problem it looks like this could or should be
fixed by either removing the extraneous copies (patch below) or by
moving them to a make install target.

If nobody objects - can someone review and push this.

Thanks
