Yes.  That is how I read it.

Look for sys/$(sys_dir)/machine/$(machine_dir)...  Those loops that copy
headers must appear after any of your added sys/$(sys_dir)/machine/*.h loops.
There are multiple stanzas because one target puts the header files in a build header 
file area.  The second installs the header files.  Not all build header files are
installed.  The restriction I mention applies in both places.  From
what I could see, you added one of your loops at the end of all other loops.
