* Test for preferred libtoolize15/libtoolize14 before trusting

    that libtoolize's version is sane (at least on freebsd, it isn't)

  * Ask the selected libtoolize for the libtool_m4 path corresponding
    to *THIS* version of libtoolize, so we remain in sync.  

    LIBTOOL_M4 continues to override the user's choice [although this
    should either become unconditional, e.g. replace libtool.m4 even
    when installed by libtoolize, or become a last resort, preferring
    the libtool_m4 envvar from libtoolize over LIBTOOL_M4 user choice.
