commit 66e2c3ba116a6f66b437d479fd89564090ef96fa
Author: Oron Peled <oron.peled at xorcom.com>
Date:   Sun Dec 21 10:29:35 2014 -0500

    autotools: now "make distcheck" also works.
    
    * Fix distcheck by having all the targets installed under $prefix
    * But by default (no prefix or prefix=/usr), revert to older pathes:
      - /etc/dahdi
      - udev rules in /etc/udev/rules.d
      - perl in perl sitelib
      - man pages in /usr/share/man
    * Add configure options:
      --with-udevrules= (e.g.: /lib/udev/rules.d)
      --with-perllib= (e.g.: `perl -V:vendorlib)
