Actually I think it isn't harmless.

Suppose this code gets triggered in lib/Makefile and src/Makefile.
The first time we run automake on both.
The next time we might run `automake src/Makefile; ...; automake lib/Makefile'
This will change the variable name and result in spurious
changes to the Makefile.in.  People notice and complain about this
sort of thing; that's why we use `sort' in so many places.
