gnu: openmpi: Remove references to compiler pathnames in "_info" programs.
This reduces the closure greatly, but note that the Fortran .mod files are gfortran version-specific, so there should probably be development packages for each incompatible version. (The runtime is supposed to be more-or-less version-independent unless the libgfortran soname changes.) There may still be a case for a separate runtime output. * gnu/packages/mpi.scm (openmpi)[arguments]: Add "remove-absolute" phase. Co-authored-by: Ludovic Courtès <ludo@gnu.org>
