Given that everything ends up in one Makefile, I don't think that 
including any given .mk file more than once is going to work at all. 
The strategy of incuding common .mk files into a per-directory 
Makefile is to support recursive build schemes.

Nothing prevents from using a script which builds specialized .mk 
files for each subdirectory.  A template file can be used with 
substitutions performed on it to localize it for the subdirectory. 
If there are a great many similar subdirectories, the same script can 
write a .mk file with include statements to also include the many 
subdirectory fragments.

When I converted my project to be non-recursive, it was before 
Automake included any special support for includes in non-recursive 
builds.  I hard-coded the sub-directory offset inside each included 
.mk file via a definition and then built all needed definitions based 
on that.  I did not even trust += syntax (due to lack of control over 
order) so everything is explicit.  This was ok since there were not 
hundreds of subdirectories.
