Subject: [PATCH] Make it easier to compile this from a script

A few changes to make it easier to compile from a script overriding some of the symbols with environment variables and using `make -e`
For example, I can now compile on linux using:
```
DYNLDFLAGS="-shared" CC=mpicc HDF5_DIR=/scratch/gdsjaar/seacas-async DYNEXT=so make -e
```
