You have to rebuilt the entire stack from source, and the debian/rules
"clean" target is your friend if the upstream build system doesn't help you.
It is normal to have these intermetidate files in the tarball to ease the
life of the 'download source and build' user, and the distros are used to
dealing with it.

Sorry, I don't have the canned reply, but you can tweak what automake things
should go into the dist target, and use make distclean and make dist.

Frankly, the easiest and least error-prone solution is to have custom clean
rules that nuke these autogenerated files, and use the usual makefile
machinery to make sure they get rebuilt when missing.

You might get even better help from the autotools mailinglists, since none
of your questions are really Debian-sepecific.
