[AMBER-Developers] A treatise on the unfortunate side-effects of the obliteration of MPI_HOME

It breaks cuda_parallel:

/usr/local/cuda/bin/nvcc -use_fast_math -O3 -gencode
arch=compute_13,code=sm_13 -gencode arch=compute_20,code=sm_20 -DCUDA -DMPI
-DMPICH_IGNORE_CXX_SEEK -I/usr/local/cuda/include -IB40C
-IB40C/KernelCommon -c kForcesUpdate.cu
In file included from gpu.h:15,
                 from kForcesUpdate.cu:14:
gputypes.h:24:17: error: mpi.h: No such file or directory


I'm going to work on a way of getting the NVCC_INCLUDES to add this
directory without resorting back to MPI_HOME based on the location of mpif90
(but MPI_HOME will override it).

This is Linux + Intel compilers. Anyone else seeing this? I get it in the
current tree as well as AT15+Amber11.

I'll submit my fix shortly.
