I think that's because when you reconfigure your project and run
aclocal it will always overwrite aclocal.m4.  So you end up
having aclocal.m4 which is newer than, and this
triggers the autoheader rule.  

Actually, the first build after each run of aclocal will trigger
this (in your story that would be `make', not `make dist', so
maybe I'm commenting something else :)).

So you should probably make a dummy build with your devel-PATH
right after any reconfiguration (to make sure all timestamps are
ok), and only then attempt to remove automake from your PATH.

BTW, maybe you will want to use a my-distcheck target that make
a build with all AUTO* variable to false (like what is done in
fileutils) to make sure your users won't ever get such an error.
