Benjamin Hipple 6206a342e0 mkl: include Intel's libiomp.so in the MKL RPM unpack ... Since Intel's default openmp implementation is available in the same src tarball, we can just include it in the package. This means that `mkl` now "just works" without any environment variables, fragile setup-hooks, or forced propagation. Since the openmp implementation is only needed at runtime (and for test cases), users can substitute a different one if they prefer by exporting it with `LD_PRELOAD`, which is how Intel recommends handling this. If they do not do so, `libiomp.so` lives next to `libmkl_rt.so` and thus will be in the RPATH as a sane default. Since this still comes from the same src tarball, we can ship it without losing the fixed-output derivation; likewise, since Hydra is not building or caching these, shipping these proprietary packages costs no bandwidth for the nix community.		2018-12-19 22:05:22 +01:00
