Although I haven't enhanced rebase as described above, I have determined
why rebase doesn't consider the Dakota DLLs rebaseable.  The first check
rebase does is to make sure a DLL is a valid PE file.  The second check
is to make sure it is relocatable.

The Dakota DLLs fail the PE check.  This can also be demonstrated by
using file:

    $ file *.dll
    PHXCppApi.dll: MS-DOS executable (EXE), OS/2 or MS Windows
    mpich.dll:     MS-DOS executable (EXE), OS/2 or MS Windows
    mpichd.dll:    MS-DOS executable (EXE), OS/2 or MS Windows
    mpicherr.dll:  MS-DOS executable (EXE), OS/2 or MS Windows

How were the Dakota DLLs built?  This could affect their ability to be
rebased.
