    doc: add XORG_CHECK_SGML_DOCTOOLS to detect xorg-sgml-doctools
    
    Trying to find X11/defs.ent with AC_CHECK_FILE does not work when
    cross-compiling, and the check assumed that xorg-sgml-doctools is
    installed to the same prefix which need not always be the case.
    
    xorg-sgml-doctools 1.4 provides a pkg-config file which we can use
    instead, fixing both those cases.  This macro is provided in util-macros
    instead of with xorg-sgml-doctools, otherwise the latter would become a
    hard dependency just to run autoreconf.
