When using the back-sql with the Oracle XE DB, the Oracle ODBC library
libsqora.so.10.1 was designed to be linked against the unixODBC interface
library instead of the iODBC interface library.  This can be demonstrated by
using the unixODBC isql tool which will  allow successful interactive querying
of the Oracle DB.  However, when trying to start up the slapd daemon with 'slapd
-d 1' the daemon will quit with an error claiming:
   Message:           [iODBC][Driver Manager]
/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib/libsqora.so.10.1:
undefined symbol: bcuMsgBoxError

The cause for this is that the configure script will first search for iodbc,
then odbc, and thus cause slapd to be built against the iodbc library.
By adding the -with-odbc option the configure script will allow the
administrator to choose which library to use in a flexible way:

  --with-odbc=iodbc                 # current default (-liodbc)
  --with-odbc=odbc                  # try -lodbc
  --with-odbc=/usr/lib/libodbc.so.1 # link against the shared object library

The changes have been made to the source configure.in file and uploaded as a
patch.
