Subject: [PATCH] Added a new shell script 'touch-autofoo.sh' :

Run from the root of $srcdir to touch the autotools generated files
so that the build procedure doesn't attempt to regenerate them.

Would be useful for preparing a release, e.g.
$ ./build-scripts/touch-autofoo.sh && ./configure && make dist
