Teach ./configure to rerun autoreconf --no-recursive

Browse source 
Currently, the ./configure script generated by autotools will
test if the configure.ac script is newer than its output configure
script, and if so, run autoconf to rebuild it. However autoconf
is no longer sufficient because we have some m4 macros. So now
run autoreconf --no-recursive (per #3572)
