Not out-of-the-box, but our packages are essentially bash scripts, so it
should be pretty easy to hack the package manager to insert a line or
two that rebuilds everything whenever e.g. configure.{in,ac} is present.

As a proof-of-concept, adding

  pre_src_prepare() {
      [[ -f configure.ac || -f configure.in ]] && autoreconf -fi
  }

to /etc/portage/bashrc [0] seems to work in the few simple cases I tried.
