Replace AC_CONFIG_FRAGMENTS, AC_CONFIG_FRAGMENTS_DEFUALT,
AC_SET_BUILDTOP, AC_CONFIG_AUX_DIR_DEFAULT with V5_SET_TOPDIR. This
sets up the correct variables for the top of the source tree and the
top of the build tree. It currently depends on AC_LOCALDIR being a
relative pathname, but that's a safe assumption to make. (And we
could fix it to be more general if we really needed to.)
Removed AC__CONFIG_AUX since it doesn't seem to be used at all.
