This patch is being submitted on behalf of Anthony Liguori of IBM. It updates
configure.in to work with autoconf 2.5x.  The current configure.in does not work
with autoconf 2.5x for two reasons: 
1) there is an outdated macro in aclocal.m4 and
2) as of autoconf 2.50 using the variable LIBOBJS for conditional object
compilation is deprecated and as of autoconf 2.53 using LIBOBJS generates
an error.  The preferred mechanism is now AC_LIBOBJ.

Also, AC_PREREQ has been changed to reflect this dependency (which is now 2.50
instead of 2.10).
