Do you have details of exactly how this changed the sysdeps directory 
ordering - what directories were removed, added or moved to what other 
locations by this change?

Because of the obscurity of the present sysdeps logic, it's a good idea 
for any such change to include the consequent diffs to the list of sysdeps 
directories - and to check in such a case for any files for which the 
patch might unexpectedly change what version of the file is found.  
Preferably, building with just the Implies change and no other change 
should not result in any changes at all to installed headers or stripped 
installed libraries.
