    Check for a proper sed program during configure
    
    * configure.ac: Call AC_PROG_SED to check for a proper sed program.
    * Makefile.am (subst_manpage): Use $(SED) variable.
    * build/dist-changelog.am (dist-changelog): ditto, in the expectation
    that most modules using mm-common already assign $(SED) in one way or
    another.
