Added ECMD_DLL_FILE_FIXED support (#272)
Added ECMD_DLL_FILE_FIXED support (#272)

* Added ECMD_DEFAULT_DLL_FILE support

This allows an at build time definition of the ECMD_DLL_FILE to
load.  This removes the need for the ECMD_DLL_FILE to be set in
the environment.

This is designed for static install situations where the location
of the libraries doesn't change.  However, it still supports the
use setting ECMD_DLL_FILE if needed.
