I think the autotools-dev README needs to be updated because the
example does not seem quite right.
If that is the intent then the -c, --no-create options to touch should
probably be used. Otherwise touch won't fail in the case of the error
the README was concerned about. In which case the && chaining is not
useful.
touch --no-create configure.ac \
&& touch --no-create aclocal.m4 \
&& touch --no-create configure \
&& touch --no-create config.h.in \
&& touch --no-create $(find . -name Makefile.in)
