ins_make install the Makefile in the directories

Usage :
  ${b_n} [-h] [-v] [-d] [-p r] [-t h] [-m m]

Options :
  -h   : help
  -v   : verbose mode
  -d   : debug mode
  -p p : int and real precision I4R4/I4R8/I8R8/4/8
  -t h : target host_name
  -m m : mpi context choosen for the coupling MPI1/MPI2

Defaults :
   -t local_host -p I4R8

Example for remote host compilation :
  ins_make -t sx8brodie
