[xml] minor shell error in configure

[stan boehm philips com]

If anyone is interested, I believe that at or about  line 3845 of
configure, it should read:


if  [ "${NEED_TRIO}" = "1" ] ; then

         or

if test "${NEED_TRIO" = "]" ; then


instead of 


if "$NEED_TRIO" = "1" ; then



This small error really messed up my build.   I went looking
for  the trio stuff, only to later find that it is now included as
part of xmllib2-2.3.8 tar ball.
