Comment (by Chris Johns):

 Solving this problem requires:

 1. Capturing the installed headers files with an MD5 checksum so each can
 be clearly identified in the source tree.
 2. Capturing the `preinstall` view of the process with the install path
 and a source tree path.
 3. Defining the include paths in RTEMS and any macros required to
 reference the header within that tree.

 For each preinstall header we need to collate the source headers and
 determine what overlaps. With the define directories we want to have we
 can determine the moves we need. I am getting close to having this data.
