I guess this is because (a) you run "make bootstrap" each time, and
(b) "make bootstrap" changes some files in the source tree.

My suggestion at this point would be to use just

   ./configure <for whatever>
   make
   make install

There should be no need for you to bootstrap when you are building a
release tarball.  Bootstrap is for building from the Git repository.
