Would it not be possible to place the _common case_ version of md_root.c
into the MI directories.  Those architectures which require a slightly
different implentation continue to use their existing MD versions.

The files.${ARCH} file can point to the MI or MD version on a case by case
basis.  Maintaining 20+ copies of the same file for the sake of 1 or 2
exceptions may not be the best solution...
