If AUTOMAKE_OVERRIDE=YES then we touch files in ${WRKSRC} in such a way

that GNU autoconf/automake are not executed during the build process, even
if the tools exist in the build environment.  This prevents the build
process from overwriting any changes made to the configure script or to the
Makefile.in files.
