[PATCH] contrib/patch_tester.sh, 1 of 7

[Janis Johnson]

Tom's patch to contrib/patch_tester.sh reminded me that I have several
changes to it that I've been using locally.  If some of them aren't
accepted into the version in contrib/ I can continue to use a local
version of the script, but probably most of them will be useful to
others as well.

I have not tested the patches individually but have used the complete
set for my own testing recently.

This one invokes contrib/gcc_update to touch generated files so the
build won't try to do that.

Sebastian, OK for trunk?
