Adding patch to MPI to disable its Makefile so people don't try

to work around TXR build problems by running make inside
the MPI directory, which is wrong.

Also fixing an incorrect use of ctype.h functions in
MPI and one case of a superfluous warning.

* mpi-patches/series: new patches added.

* mpi-patches/disable-make: New file.

* mpi-patches/fix-ctype-warnings: New file.
