Comment (by guibou):

 @mpickering, thank you for the workaround. Do you think this can be
 considered as a packaging issue (of `libgsl`)? or is this still a ghc
 issue considering that it works without `-fexternal-interpreter`?

 I tried to flip `gsl` and `gslcblas` in `external-libraries` and it does
 not change anything.
