The generated-configure.sh script is dead - autoconf seems to write into the sources in the build process

Hi Volker and Matthias,
I'm sorry I missed this usecase. :-(
I think the patch is OK. I'm just thinking about the "make reconfigure"
case. I guess it works as long as you call "make reconfigure" from the
same directory, but then again, that's probably the likely way to work
in this case. It will *not* work in the case that you do e.g.:
mkdir -p build/mybuild && cd build/mybuild
bash ../../configure
cd ../..
make CONF=mybuild
but then again, mixing "methods" like that is perhaps not so common, and
the only penalty is that we get two .build directories.
Maybe we should even use "configure-support" instead of ".build" as
build_support_dir for the "outside of src dir" case? It would certainly
fit in better with already existing structure in the build output directory.
