I'm not sure "./configure && make && make install" as it is now is
better than providing a single "" script. At least, name ""
does not come with (implied) promise to be like configure in any respect.

For another example, trying to use Boost's configure in buildir != srcdir
scenario, that is going to some directory and saying "<boost-src-dir>/configure"
does not seem to work either, and this is commonly used feature of auto*.
