[bug#27344] [PATCH v3 1/8] gnu: Add asco.

[Theodoros Foradis]

One additional note for this package regarding mpi and cross-compiling.

This is the relevant part of the Makefile (this package is not using
autotools):
CC_MPI = <path-to-mpi-package>/bin/mpicc
asco-mpi:
        $(CC_MPI)  $(CFLAGS) -DASCO -DMPI ...

I assumed openmpi should be a native input, because mpi-cc is used. If
this is a mistake, and it won't work when cross-compiling, we can omit
building asco-mpi altogether.
