Unaligned access messages on Linux Itanium platform

[CR #499382] For Linux Itanium users, if you run sqlupgrade[res], srvbuild[res], or sqlloc[res], you will see "unaligned access ..." messages.

Workaround: To hide them run the application with this command where <program-name> is either sqlupgrade[res], srvbuild[res], or sqlloc[res]:

prctl --unaligned=silent <program-name>
