Well, you have:

XSLT_LIBS="-lxslt $LIBXML_LIBS $M_LIBS"
EXTRA_LIBS="$LIBXML_LIBS $M_LIBS"

It seems to me that LIBXML_LIBS will always contain M_LIBS already, but
if you are worried about that, then instead of just removing M_LIBS,
you can do:

====
EXTRA_M_LIBS=""

changequote(,)dnl
if test "x$M_LIBS" != "x" ; then
  case " $LIBXML_LIBS " in
  *[\ \	]$M_LIBS[\ \	]*) ;;
  *) EXTRA_M_LIBS="$M_LIBS" ;;
  esac
fi
changequote([,])dnl

XSLT_LIBS="-lxslt $LIBXML_LIBS $EXTRA_M_LIBS"
EXTRA_LIBS="$LIBXML_LIBS $EXTRA_M_LIBS"
====

[ The shell / m4 magic here is derived from things that have been in the
  GTK+ configure.in forever, so I'm reasonably confident about its
  correctness and portability ]
