Remove annoying autoconf warning

Under autoconf 2.64 and newer the current autoconf macros of SXEmacs emit the following
warning multiple times:

_LT_SYS_DYNAMIC_LINKER was expanded before it was required

   * m4/sxe-libtool.m4 (_SXE_CHECK_LT2): Add AC_REQUIRE for
     _LT_SYS_DYNAMIC_LINKER as recommend by
     http://www.gnu.org/software/autoconf/manual/autoconf.html#Expanded-Before-Required
