According to https://software.intel.com/en-us/articles/intel-mkl-link-line-advisor/ it is well possible to for example use Intel OpenMP (libiomp5) with GNU GCC.
Furthermore does Intel always recommend to link against mkl_intel_lp64 instead of mkl_gf_lp64.
Plus, when selecting mkl64-dynamic-openmp we always link in Intel OpenMP while the link line advisor says to not use any OpenMP specific flags or libraries.

It it is well possible that the link line advisor has some bugs too, in that case we probably need some documentation...

... and shouldn't -fopenmp be added to Cflags instead of Libs (now for mkl64-gfortran-openmp)?

Does this bug still applies with mkl-2020?

The new ebuild installs the pkg-config files and configuration supplied by intel. So we're good.
