Description: Allow compilation with gfortran 10
 In gfortran 10, mismatches between actual and dummy argument lists in
 a single file are now rejected with an error.  This is causing a
 compilation error for file src/optimal_interpolation.F90 (in the call
 to LAPACK's function dsyev), which makes the package fail to build.
 The problem is avoided by using the new option
 -fallow-argument-mismatch in FFLAGS.
