Fix building in serial.

That is, without MPI: `./configure --without-mpi`.
Merge pull request #85 from QuLogic/serial

Fix building in serial.
build: Make changes to scotch build permanent.

Every time you configured with internal scotch, you'd get modifications
to its Makefiles which git would show as modified. This is troublesome
whenever you want to commit or change branches, because you'd have to
remember not to keep those changes.

The changes to the scotch Makefiles are independent of any options you
might pass to configure (except that they aren't done if you aren't
using internal scotch). We can just make them permanently in git,
especially because the changes have been made upstream in scotch as
well.
build: Remove backup Makefile targets.

These commands are a relic of a non-distributed VCS. Now, if you need to
backup your work, just make a commit. No-one else has to see it, but
it's a lot safer that way. And if you don't want to go through the
trouble of a commit, just run `git stash` instead.
build: Remove unnecessary creation/deletion of directories.
build: Remove extra build script.

There are already makefile rules for these programs.
build: Remove forced re-compilation.
build: Remove extra targets from generate_databases.

These targets don't exist in this directory.
build: Fix rules for executables.

Since the executables were never mentioned by full path, they would be
rebuilt unconditionally.
build: Fix scotch dependency of decompose_mesh.F90.

Without this dependency, parallel builds fail due to missing scotchf.h.
build: Add module dependencies to rules.

This should fix parallel builds by ensuring modules are created before
they are used by any source files.

Fixes #84.
Merge pull request #86 from QuLogic/parallel-make

Fix parallel make
build: Fix dependencies for ADIOS objects.

I accidentally used ADIOS_PRESTUBS instead of ADIOS_PREOBJECTS, which
obviously uses the wrong object when building with ADIOS enabled.
Fix compile with ADIOS enabled.

Three issues:
* Some string constants were split without the join operator (//) between
  them.
* The error "Procedure 'read_model_vp_rho_adios' at (1) with assumed-shape
  dummy argument 'rho_read' must have an explicit interface".
* Some incorrect sizing of an array, followed by accessing unallocated
  indices, could cause a crash.
build: Fix rules for xmodel_update.

Missing some options for the include directory and linking with the
ADIOS libraries.
